Modernizing Routine HPLC Methods: Aligning Productivity, Compliance, and Sustainability

<h3>How to Easily Adapt Your Existing HPLC Methods</h3>Developing and optimizing an HPLC method is essential for achieving reliable separations, accurate quantification, and reproducible analytical results. As chromatography technology advances, one of the most common optimization strategies is transferring established methods to modern columns with smaller dimensions.Although the benefits are clear, many analysts hesitate when it comes to modifying a validated method.<blockquote>Questions quickly arise: How should the flow rate be adjusted? What injection volume is appropriate? Does the gradient need to be recalculated? Will the retention times change?</blockquote>Even with the necessary equations available, performing all these calculations manually can be time-consuming and prone to errors. Instead of simplifying the workflow, method transfer often becomes an unnecessary obstacle.Fortunately, there is an easier solution.<h4>Simplify Your HPLC Method Transfer</h4>Moving an existing method to a different column does not have to be complicated.The KNAUER HPLC Method Converter is designed to automate the calculations required for method transfer. Simply enter the parameters of your current method, including the original column dimensions, and specify the dimensions of the new column—length, internal diameter, and particle size. The software instantly calculates the recommended flow rate and injection volume for the new conditions.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/KNAUER_HPLC_Method_Converter_7f7c19f7a3.webp" alt="KNAUER: HPLC Method Converter" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_KNAUER_HPLC_Method_Converter_7f7c19f7a3.webp 210w," sizes="100vw" width="1022" height="759">The next step is equally straightforward. Copy the original gradient profile into the converter, and the software automatically generates the corresponding gradient program for the new column.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/KNAUER_HPLC_Method_Converter_2_8ba46e78bc.webp" alt="KNAUER: HPLC Method Converter - Gradients" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_KNAUER_HPLC_Method_Converter_2_8ba46e78bc.webp 195w," sizes="100vw" width="1440" height="1150">For even greater confidence, the converter also allows you to enter chromatographic peak information. Based on these data, it predicts the expected retention times under the new conditions. While experimental verification on the HPLC system is still recommended, these predictions provide an excellent starting point for method optimization.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/KNAUER_HPLC_Method_Converter_3_34f16bb3bf.webp" alt="KNAUER: HPLC Method Converter - Chromatograms" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_KNAUER_HPLC_Method_Converter_3_34f16bb3bf.webp 196w," sizes="100vw" width="1024" height="814">The converter was developed with one primary objective: making HPLC method adaptation faster, easier, and more reliable while reducing the effort required from the user. Its intuitive interface, modern design, and automatic calculations help save valuable laboratory time—and it is available free of charge.<h4>Modernize Your Methods and Improve Laboratory Efficiency</h4><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/KNAUER_HPLC_Method_Converter_4_31e7188db4.webp" alt="KNAUER: Modernize Your Methods and Improve Laboratory Efficiency" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_KNAUER_HPLC_Method_Converter_4_31e7188db4.webp 245w," sizes="100vw" width="720" height="449"><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/KNAUER_HPLC_Method_Converter_5_815a7bf889.webp" alt="KNAUER: HPLC Method Converter - Results" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_KNAUER_HPLC_Method_Converter_5_815a7bf889.webp 194w," sizes="100vw" width="1440" height="1157">One of the major advantages of the KNAUER HPLC Method Converter is its compliance with USP General Chapter &lt;621&gt;.For pharmaceutical laboratories, chromatographic methods must comply with pharmacopeial requirements that ensure product quality and patient safety. Historically, many USP methods were developed using larger HPLC columns that no longer reflect the capabilities of modern chromatography systems.Current USP, European Pharmacopoeia (Ph. Eur.), and Japanese Pharmacopoeia (JP) guidelines now permit specific adjustments to column dimensions and particle size for both isocratic and gradient methods. These changes are allowed provided that defined relationships between chromatographic parameters are maintained.The KNAUER Method Converter automatically checks whether the selected column dimensions remain within the permitted USP limits. If the proposed changes comply with the guidelines, the software confirms that the method can be transferred while remaining pharmacopeia compliant. This removes uncertainty from the method conversion process and helps laboratories modernize their analytical workflows with confidence.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/KNAUER_HPLC_Method_Converter_6_c9d1e28c54.webp" alt="Unsplash: Illustrative picture" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_KNAUER_HPLC_Method_Converter_6_c9d1e28c54.webp 245w," sizes="100vw" width="720" height="449"><h4>Increase Productivity While Reducing Solvent Consumption</h4>Updating HPLC methods is not only about shortening analysis times—it also supports more sustainable laboratory practices.Using shorter columns together with optimized flow rates significantly reduces solvent consumption, lowering operating costs and decreasing the amount of hazardous chemical waste generated during routine analyses. Faster separations also improve instrument throughput, enabling more samples to be processed within the same amount of time.Modernizing chromatographic methods therefore delivers a dual benefit: greater laboratory productivity and a smaller environmental footprint. With only a few simple adjustments, laboratories can improve efficiency while supporting more sustainable analytical workflows.

Agilent Technologies: Determination of 41 Per- and Polyfluoroalkyl Substances (PFAS) in Cosmetics</h3><ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_captiva_emr_pfas_food_ii_cartridge_5994_9111en_agilent_be91861646.pdf">Full PDF for download</a></li></ul>Per- and polyfluoroalkyl substances (PFAS) are synthetic compounds composed of highly stable carbon–fluorine (C–F) bonds, giving them exceptional thermal and chemical stability, leading to poor environmental degradability. PFAS have been used in cosmetics to provide water resistance, oil repellency, or application smoothness. The unintentionally presented PFAS residues in raw materials may remain in finished cosmetic products, and can be absorbed through the skin. Lip products and spray type products can also lead to inhalation or oral exposure to residues.1,2&nbsp;Agilent Captiva EMR PFAS Food cartridges are designed to provide streamlined and comprehensive matrix removal after QuEChERS extraction for complex sample matrices, demonstrating effective matrix cleanup efficiency and excellent performance for quantitative PFAS analysis.3,4 In this study, we performed QuEChERS extraction followed by cleanup with Captiva EMR PFAS Food II cartridges for PFAS analysis in five types of cosmetics.<h4>Experimental</h4><h5>Equipment and materials&nbsp;</h5>The study was performed using an <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/library?mainauthorItems=10&amp;search=1290+Infinity+III">Agilent 1290 Infinity III LC</a> system consisting of an Agilent 1290 Infinity III high-speed pump (G7120A), an Agilent 1290 Infinity III multisampler (G7167B), and an Agilent 1290 Infinity III multicolumn thermostat (G7116B). The LC system was coupled to an <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/library?mainauthorItems=10&amp;search=6495D">Agilent 6495D triple quadrupole LC/MS system</a> (G6495D) equipped with an Agilent Jet Stream Electrospray ion source. Agilent MassHunter Workstation software was used for data acquisition and analysis.&nbsp;The 1290 Infinity III LC system was modified using an Agilent InfinityLab PFAS Analysis HPLC conversion kit (part number 5004-0006), including an Agilent InfinityLab PFC delay column, 4.6 × 30 mm (part number 5062-8100). Chromatographic separation was performed using an Agilent <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/library?mainauthorItems=10&amp;search=ZORBAX+RRHD+Eclipse+Plus">ZORBAX RRHD Eclipse Plus</a> C18, 95 Å, 2.1 × 100 mm, 1.8 µm (part number 959758-902).<h4>Results and discussion&nbsp;</h4><h5>Chromatography and calibration curve linearity&nbsp;</h5>Figure 2 shows the overlaid chromatograms for 41 PFAS calibration standards, including 0.05, 0.1, 0.2, 0.5, 1.0, 2.0, 5.0, and 10.0 ng/mL in ACN. The table on the right shows the peaks identification and corresponding retention time. Across 41 PFAS compounds, R² values ranged from 0.9940 to 0.9998, indicating excellent linearity for all analytes' calibration curves across the calibration range of 0.05 to 10.0 ng/mL.<h5>PFAS detection in real cosmetic samples&nbsp;</h5>Of the 15 cosmetic products assessed, one eyeshadow sample was detected with a trace level of positive PFAS analytes, including PFHeA, PFHpA, PFNA, and PFOA, at about 0.1 ng/g in the sample. Figure 5 shows the method blanks and positive detection of PFHpA and PFNA in this eyeshadow&nbsp;product.<h4>Conclusion&nbsp;</h4>A simplified, rapid, and reliable method using QuEChERS extraction followed by EMR mixed-mode passthrough cleanup using the Agilent Captiva EMR PFAS Food II cartridge and LC/MS/MS detection was developed for 41 PFAS analysis in cosmetics.<h3>2. Metrohm: brightRC – Advanced brightener analysis with a response curve</h3>Next-level brightener determination in nonlinear systems<ul><li>Application note</li><li><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/an_v_242_download_83376b2923.pdf">Full PDF for download</a></li></ul><h4>WHAT IS BRIGHTRC?&nbsp;</h4>brightRC is a response curve calibration approach for the determination of brightener-type additives by CVS or CPVS (Cyclic Pulse Voltammetric Stripping), hence the name «brightRC». This technique is suitable to measure brightener content in copper baths for plating. The method is based on signal normalization using the electrolyte value, which is the response for the virgin makeup solution (VMS) saturated with suppressor, and brightener defined as Q0 in the viva software. All recorded signals are divided by Q0 and the normalized values are plotted against concentration to generate an external calibration curve. This calibration can then be used for routine sample determination without repeated standard additions.&nbsp;The sample is simply measured using the same method as the calibration, signals are normalized and evaluated using the mathematically fitted calibration curve. By decoupling calibration from sample measurement, brightRC removes the need for repeated standard additions with each sample measurement, enabling faster and more efficient routine analysis.&nbsp;The brightRC calibration approach supports flexible regression models including quadratic and nonlinear regression. This allows reliable quantification of additive systems that do not exhibit a wide linear working range or exhibit nonlinear response characteristics, thereby expanding the range of applicable brightener chemistries.&nbsp;One important detail that further differentiates brightRC from the MLAT approach relates to normalization of the signal for calibration and sample analysis. This normalization approach improves measurement robustness as variations in absolute signal intensity naturally occurring over the working day are mathematically compensated.<h4>HOW DOES BRIGHTRC WORK IN PRACTICE?&nbsp;</h4>The brightRC workflow separates calibration and sample analysis. It can be implemented in different setups (from manual to fully automated) depending on the additive system and concentration range. After recording the electrolyte value, calibration standards are measured to establish the calibration curve, otherwise known as the response curve. Once the calibration is stored, samples are determined with the same CVS or CPVS method, without further standard additions. The sample concentration is automatically calculated from the normalized signal using the calibration curve.&nbsp;For sample measurement, viva 4.0 provides two practical approaches:&nbsp;<ol><li>«brightRC with solution exchange»&nbsp;</li><li>«brightRC with sample dilution» Both variants follow the same calibration principle and differ only in the sample handling strategy.</li></ol><h4>WHEN TO USE BRIGHTRC?&nbsp;</h4>brightRC is ideal for routine brightener control in stable plating baths where high sample throughput is required. It is particularly suitable when matrix conditions are consistent and electrode fouling is limited. The approach is especially advantageous for additive systems exhibiting nonlinear signal behavior. If strong matrix variations, significant breakdown products, or severe electrode fouling are expected and a linear correlation between signal and analyte concentration is guaranteed, standard addition techniques such as MLAT are preferred because they may provide additional robustness.<h3>3. Shimadzu / ASMS: PFAS Analysis of Leachate: Evaluating Key Sample Preparation and LC–MS/MS Parameters for Improved Performance</h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/WP_255_PFAS_Analysis_of_Leachate_Evaluating_Key_Sample_Preparation_and_LC_MSMS_Parameters_for_Improved_Performance_1114ee264c.pdf">Full PDF for download</a></li></ul>Landfill leachate is a highly complex and variable matrix that poses significant challenges for the analysis of per- and polyfluoroalkyl substances (PFAS). Although U.S. Environmental Protection Agency Method 1633A provides a standardized framework for PFAS quantitation,1 analytical performance remains strongly influenced by sample preparation, chromatographic separation, and mass spectrometric conditions. Landfill leachate samples were extracted using WAX SPE following EPA 1633A and analyzed by LC–MS/MS using a <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/library?mainauthorItems=1&amp;search=LCMS-8060">Shimadzu LCMS-8060</a> under negative ESI conditions. This study evaluates the key factors governing LC–MS/MS sensitivity, signal response, and reproducibility in landfill leachate, including a systematic assessment of SPE, chromatographic behavior, and ionsource conditions across PFAS classes (Figure 1).<h4>Results&nbsp;</h4>Chromatographic performance was evaluated across four C18 columns (A–D) using peak area, height, asymmetry, and HETP. Two columns produced a higher signal and improved peak shape, while the remaining columns showed greater efficiency. Under repeated batches followed by storage in acetonitrile, the Shimadzu GIST column produced a consistent signal (≤15% change), whereas another column showed 20–50% signal loss, particularly for long-chain PFAS and precursors, indicating greater susceptibility to matrix accumulation (Figure 2).<h4>Conclusion&nbsp;</h4><ul><li>PFAS analytical performance was dependent on compoundclass-dependent extraction, chromatography, and ionization behavior.&nbsp;</li><li>GIST demonstrated lower signal variability under repeated matrix exposure, with lower signal degradation than alternative C18 phases.</li><li>Neutral PFAS showed poor retention on WAX sorbents, requiring optimization beyond standard EPA 1633A extraction conditions.&nbsp;</li><li>PFCA response was more influenced by gas flow conditions, whereas PFSA response was more sensitive to source temperature conditions.</li></ul><h3>4. Thermo Fisher Scientific / ASMS: Ultra-high throughput proteomics at &gt;500 samples/day using advanced <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/398">Vanquish Neo UHPLC</a> methods with <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/1959">Orbitrap Astral Zoom MS</a></h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/po_004708_lsms_ultra_high_throughput_vanquish_astral_proteomics_po004708_asms2026_na_en_f6499c3eec.pdf">Full PDF for download</a></li></ul>High-throughput mass spectrometry is increasingly critical for large-cohort proteomics, population-scale studies, and screening applications. While established LC–MS platforms routinely support several hundred samples per day, further increases in throughput are often limited by chromatographic stability, robustness, and reproducibility under ultra-short gradient conditions, as well as the acquisition speed of the mass spectrometer. Here, we describe an advanced ultra-high-throughput LC–MS methodology developed on the Thermo Scientific Vanquish Neo UHPLC system and Thermo Scientific Orbitrap Astral Zoom mass spectrometer. The goal of this work was to extend the practical throughput limits of LC–MS while achieving deep proteome coverage and maintaining run-to-run reproducibility.<h4>Materials and methods</h4><h5>LC-MS analysis&nbsp;</h5>Samples were separated on a Thermo Scientific 150 µm × 70 mm C18 column (prototype, not commercially available yet) operated at 4 µL/min using a <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/398">Vanquish Neo UHPLC system</a> in NanoCap Trap&amp;Elute configuration at room temperature. Prototype methods allowing for reduced LC duty cycles (approx. 1 min of sample pickup/loading and integrated trap-column offline wash) were applied, the standard gradients were adjusted to 1 – 3 min. The Thermo Scientific PepMap Neo 5 µm C18 300 µm × 5 mm cartridge was used as trap column and the separation column connected with a 15 µm ID capillary Thermo Scientific EASY-Spray emitter (ES994) to an EASY-Spray source. The <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/1959">Orbitrap Astral Zoom MS</a> (ICSW AST 2.2) was operated in a dataindependent acquisition (DIA) mode, MS method parameters are given in Table 1. Comparative data for the chemoproteomics samples at lower throughputs (60-300 SPD) were acquired using an EASY-Spray 150 µm × 150 mm C18 column (ES906), as described before.&nbsp;<h5>Data analysis&nbsp;</h5>The raw data files were processed with Spectronaut® 20.5 software (Biognosys AG), <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/1782">Thermo Scientific Proteome Discoverer </a>3.3 SP1 with CHIMERYS 5.0 or DIA-NN Enterprise 2.3.2 (Aptila Biotech GmbH) nodes using default settings as specified in the individual figures. The data was searched against the Homo sapiens SwissProt database (TaxID=9606: 42,252 sequences) and contaminants FASTA file. Peptide numbers correspond to unique stripped peptides<h4>Conclusions&nbsp;</h4><ul><li>The advanced Vanquish Neo UHPLC methodology in combination with the Orbitrap Astral Zoom MS delivered highly reproducible, deep and precise proteome profiling across ultra-high-throughput regimes (600 SPD) exceeding current field benchmarks.&nbsp;</li><li>The workflow enables rapid chemoproteomic screening, as demonstrated with activity-based protein profiling (ABPP) samples, reliably identifying enriched putative target proteins of an antibiotic small molecule probe.</li></ul><h3>5. Waters Corporation / ASMS: Assessing Relative Response of Four European-Regulated PFAS in Human Serum Using Cyclic Ion Mobility MS</h3><ul><li>Poster</li><li><a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/labrulez-bucket-strapi-h3hsga3/720009410_c98e7c87ec.pdf">Full PDF for download</a></li></ul><div><div><section><div><div><div><div><div><div>The poster presents an LC-Cyclic-IMS-MS approach for assessing four European-regulated PFAS—PFOS, PFOA, PFNA, and PFHxS—in human serum. The study focuses on environmental exposure monitoring in Ghanaian firefighters and e-waste handlers, using ion mobility mass spectrometry to add separation power and improve identification confidence in complex biological matrices. The work is motivated by increasing regulatory concern around PFAS toxicity, bioaccumulation, and the need for reliable exposure assessment in human biofluids.The experimental workflow combined reversed-phase LC with a quadrupole-cyclic ion mobility-time-of-flight MS system (<a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/202">SELECT SERIES Cyclic IMS</a>). Human serum samples were prepared using SPE µElution plates with a polymeric reversed-phase/weak anion exchange sorbent. The LC system was modified with PFAS-free components and an isolator column to reduce background contamination, which is especially important for trace-level PFAS analysis. Identification was supported by retention time, accurate mass, isotopically labelled internal standards, and collision cross section values.The results showed detectable levels of the four regulated PFAS in both occupational groups, with a combined detection rate of 83% across human serum samples and NIST reference standards. Firefighter samples generally showed higher concentration ranges than e-waste handler samples, especially for PFOS, PFOA, PFNA, and PFHxS. For example, PFNA reached up to 5.713 ng/mL in firefighter serum, compared with up to 1.513 ng/mL in e-waste handler serum.Overall, the poster concludes that LC-Cyclic-IMS-MS provides a highly specific strategy for PFAS analysis in complex biological samples. Ion mobility and CCS values improve confidence in trace-level identification and help distinguish target PFAS from co-eluting matrix background. The authors suggest that this approach can support both targeted PFAS monitoring and broader non-targeted screening of known and emerging PFAS, while also helping future studies connect exposure data with environmental fate and potential toxicological effects.</div></div></div></div></div></div></section></div></div>

Analytical Method Development

How to select analytical column kit and the critical parameters for your method.

Analytical Method Development (HPLC, LC/MS, columns)

Given the numerous sources of protein variation, ranging from biological factors to sample preparation and instrument settings, there is a pressing need for next-generation analytical platforms capable of driving proteoform analysis with complete molecular precision.
In this webinar, Dr. Michael Caldwell, Scientific Officer at Northwestern Proteomics Center of Excellence, will explore top-down mass spectrometry (TD-MS) and Platinum®. Platinum is a benchtop platform that provides single amino acid resolution of single protein molecules to characterize IL-6, including pyroglutamate (pE), a post-translational modification (PTM) produced via enzymatic and spontaneous cyclization of N-terminal glutamine (Q)/glutamate (E) residues.
Find out how TD-MS enables intact protein analysis, limiting formation of N-terminal Q/E (MS1). During MS2, analysis of daughter ions reveals modifications and artifactual formation. Platinum employs dye-labeled N-terminal amino acid recognizers that reveal primary structure and variants, and aminopeptidases that expose the next amino acid for recognition until the peptide is sequenced. TD-MS and Platinum detect not only functionally relevant regions of IL-6 primary structure, but also sites prone to pE formation.

Biomonitoring of toxicants like pesticides and PFAS in humans is essential for understanding how chemical exposure affects our health, yet chemical coverage is currently limited with targeted LC-MS approaches.Untargeted data acquisition, however, is emerging as a promising tool for broader chemical coverage and understanding the possible outcomes of chemical exposure on human health.In this webinar, our expert speaker will discuss how a new method with sequential acquisition of targeted and untargeted data can be used to analyze the exposome and the metabolome in a single LC-MS run, providing greater insights into the effects of chemical exposure.Attend this webinar to:<ul><li>Find out about the benefits of sequential targeted and untargeted data acquisition in a single LC-MS run</li><li>Understand how high sensitivity and broad chemical coverage can be achieved simultaneously for performing exposomic and metabolomic experiments</li><li>Discover a novel method that can be tailored for many different applications in the field of small molecule omics</li></ul><blockquote>Presenter: Dr. Vinicius Verri Hernandes (Postdoctoral Researcher at University of Vienna)</blockquote><blockquote>Vinicius obtained his degree in Chemistry followed by a Master in Analytical Chemistry in 2013 from the University of Campinas in Brazil, with focus on mass spectrometry. He later started a joint PhD program between the same university and the Centre for Excellence in Metabolomics in Bioanalysis in Madrid, Spain, working on multiplatform metabolomics on dried blood spots. From 2018 to 2022 he worked as a postdoctoral researcher at the European Research Academy (EURAC) in Bolzano, Italy, being responsible for targeted and untargeted data generation for 5000 samples from the CHRIS populational study. Currently at the University of Vienna, Vinicius focus his work on the combination of targeted and untargeted approaches for exposomics and metabolomics, as well as in the development of analytical workflows for exposure analysis on dried blood spots.</blockquote>
