Ask any analytical chemist which hyphenated technique has become indispensable over the past decade, and the answer will almost certainly be the same: tandem chromatography–mass spectrometry. Whether it is <a target="_blank" rel="noopener noreferrer" href="https://www.organomation.com/preparing-samples-for-lc-ms/ms-analysis">LC–MS/MS</a> quantifying a novel biologic’s metabolic fate, or <a target="_blank" rel="noopener noreferrer" href="https://www.organomation.com/preparing-samples-for-gc-ms/ms-analysis">GC–MS/MS</a> chasing per- and polyfluoroalkyl substances (PFAS) down to sub-part-per-trillion levels in municipal water, the combination of chromatographic separation with the specificity of tandem mass detection has become the analytical workhorse of choice across virtually every regulated sector.Below we examine the key forces propelling this expansion, from biopharma pipeline dynamics and PFAS regulatory mandates to AI-driven automation and reshoring of pharmaceutical manufacturing—and explore what each trend means for laboratories managing sample preparation and analytical workflows.<h3>Biopharma: The Engine Room of LC–MS/MS Demand</h3><h4>GLP-1 Agonists and the Metabolomics Gold Rush</h4>The explosive commercial and scientific interest in GLP-1 receptor agonists—<a target="_blank" rel="noopener noreferrer" href="https://www.sepscience.com/advancing-glp-1-peptide-analysis-chromatography-challenges-and-innovations-12163">semaglutide and related peptide therapeutics </a>for diabetes and obesity—has dramatically expanded the analytical demands placed on tandem MS platforms. Discovery programs require precise quantification of peptide drug candidates and endogenous biomarkers across complex biological matrices. These workflows rely on high-sensitivity LC–MS/MS for pharmacokinetic profiling, receptor occupancy studies, and metabolomics characterization. Metabolomics is, in fact, projected to be the fastest-growing application segment in mass spectrometry, driven in part by its growing role in cancer screening, biomarker discovery, and metabolic disease research.I have been spending more time learning about GLP-1s because this is the hot topic that people want to discuss on the Concentrating on <a target="_blank" rel="noopener noreferrer" href="https://open.spotify.com/show/1wZg67rCjoGju4yhqxI3tL?si=n9GLz9zjSCOrVfXPxFPhng&amp;nd=1&amp;dlsi=52868e027aad4d22">Chromatography podcast</a>. With that said, I was astounded looking at CNBC.com during breakfast this morning to see that <a target="_blank" rel="noopener noreferrer" href="https://www.cnbc.com/2026/03/21/glp-1-diets-restaurants-protein-fiber-weight-loss-drugs.html">one in eight Americans are currently taking one of these drugs such as Ozempic</a>.<h4>Antibody–Drug Conjugates and Gene Therapy: Complexity at Every Step</h4>The ascent of antibody–drug conjugates (ADCs) and gene therapies has introduced a new level of analytical complexity. ADCs blend the target specificity of monoclonal antibodies with the cytotoxic potency of small-molecule payloads—and characterizing the linker chemistry, drug-to-antibody ratio (DAR), and conjugate stability demands high-resolution LC–MS/MS at every stage from discovery through QC release testing. Gene therapy vectors require equally rigorous characterization of impurities, aggregates, and empty/full capsid ratios.This translates into a direct need for low-evaporation, high-recovery concentration methods that preserve labile protein structures and maintain sample integrity prior to LC–MS/MS injection. <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/article/5392">Nitrogen evaporation workflows</a> that minimize oxidative stress and maintain sample temperature are increasingly critical in these pipelines.<h4>Precision Medicine and Multi-Omics Integration</h4>The shift toward precision medicine has accelerated adoption of high-throughput, multi-analyte MS platforms. Proteomics, metabolomics, and lipidomics workflows are converging on a single analytical platform—tandem MS—and generating datasets of a scale and complexity that were unimaginable ten years ago.Make no mistake: the triple quadrupole serves an irreplaceable role in quantitative targeted analysis. At the same time, <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products?category=134&amp;manufacturerItems=3">Orbitrap </a>and Q–TOF hybrid platforms are growing rapidly as researchers demand full-scan accurate mass for untargeted discovery.<h3>Environmental Mandates: PFAS Testing Drives Adoption</h3>Environmental testing is something that every person, chemist or not, can understand the importance of. Mounting mandates from the U.S. Environmental Protection Agency and European regulators regarding PFAS—the “forever chemicals” whose extraordinary environmental persistence is matched only by the analytical challenge of detecting them at trace levels—have created immediate, compliance-driven investment in LC–MS/MS infrastructure.<h4>The Regulatory Framework Chemists Need to Know</h4>The EPA has codified a suite of LC–MS/MS-based methods as the analytical standard for PFAS in water and solid matrices:<ul><li><a target="_blank" rel="noopener noreferrer" href="https://blog.organomation.com/blog/epa-533-drying-down-pfas-samples-after-spe">EPA Method 533</a>: Weak anion exchange SPE combined with LC–MS/MS; covers 25 PFAS including short-chain compounds in drinking water.</li><li><a target="_blank" rel="noopener noreferrer" href="https://blog.organomation.com/blog/sample-concentration-epa-method-537-pfas-determination">EPA Method 537.1</a>: Reversed-phase SPE followed by LC–MS/MS; covers 18 PFAS including the GenX compound, with method detection limits in the low ng/L range.</li><li><a target="_blank" rel="noopener noreferrer" href="https://www.agilent.com/en/solutions/environmental/water-testing/pfas-in-water/us-epa-method-8327?srsltid=AfmBOooCY1pcavj7B1PH-75d3HO4BGDglNlhmyTyrpDY3zvUksMO1dlg">EPA Method 8327</a>: LC–MS/MS for selected PFAS in prepared extracts of aqueous and solid matrices.</li><li><a target="_blank" rel="noopener noreferrer" href="https://blog.organomation.com/blog/preparing-diverse-sample-matrices-for-epa-method-1633">EPA Draft Method 1633</a>: The emerging benchmark for PFAS in non-aqueous matrices—aqueous, solid, biosolids, and tissue—quantifying up to 40 PFAS.</li></ul>All of these methods designate LC–MS/MS, specifically LC coupled to triple quadrupole or tandem-in-time platforms operating in negative electrospray ionization mode with multiple reaction monitoring (MRM), as the required or recommended analytical technique. PFAS analysis is, at its core, an LC–MS/MS problem.<h4>The Sample Preparation Bottleneck</h4>Chemists who have worked with PFAS methods understand the particular demands they place on sample preparation. The ubiquity of<a target="_blank" rel="noopener noreferrer" href="https://blog.organomation.com/blog/tackling-pfas-contamination-practical-insights-from-epa-537.1-method-development"> PFAS in laboratory materials</a>—PTFE tubing, some SPE sorbents, standard bench supplies—means that blank contamination control is as analytically demanding as the detection itself. EPA 537.1 requires that sample volumes of approximately 250 mL be extracted and reconstituted in as little as 1 mL, creating a 250:1 concentration factor that can expose even trace contamination in the sample processing chain. The installation of a delay column between the LC pump and autosampler to prevent instrument background interference is now standard practice.This is precisely where robust, <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/article/5385">inert nitrogen evaporation </a>systems earn their keep. PFAS workflows that use nitrogen-assisted evaporation to concentrate extracts prior to reconstitution benefit from materials that avoid PTFE and other fluoropolymers that can leach PFAS background—a consideration Organomation addresses in its concentration system designs.The analytical community is also moving beyond targeted PFAS analysis. High-resolution accurate mass (HRAM) spectrometry via Orbitrap technology, paired with non-targeted screening workflows, is gaining traction for the identification of the more than 5,000 currently catalogued PFAS compounds and the novel structures that continue to emerge. LC–MS/MS remains the quantitative gold standard; HRAM provides the discovery layer.<h3>Technological Trends Reshaping the LC–MS/MS Workflow</h3><h4>Artificial Intelligence and Automated Data Interpretation</h4>The datasets generated by modern tandem MS platforms—particularly in omics applications—are too large and too complex for conventional manual review. AI-driven spectral deconvolution, automated peak integration, and AI-assisted hypothesis generation are now embedded in the software suites accompanying leading instruments. <a target="_blank" rel="noopener noreferrer" href="https://www.agilent.com/about/newsroom/presrel/2022/17feb-gp22004.html?srsltid=AfmBOop3warRIaEojXM2YyMML6RXfMIDzE-Wm0h-SiKkkocBeeET2m7u">Agilent’s acquisition of Virtual Control’s ACIES </a>software specifically to automate LC–MS and GC–MS data analysis is emblematic of this direction.For laboratory managers, AI integration means smaller specialized teams can operate high-throughput multi-analyte workflows—but it also means that the front-end sample preparation must be even more reproducible, since algorithmic interpretation amplifies inconsistencies introduced upstream.<h4>Online SPE Coupling and “Chromatography Without Walls”</h4>A significant trend is the integration of solid-phase extraction directly into the HPLC flow path—so-called online SPE–HPLC coupling. Systems that combine extraction and chromatographic separation in a single analytical instrument reduce manual transfer steps, minimize the risk of sample loss or contamination, and dramatically increase throughput. For analytes at very low concentrations, online SPE provides the on-column concentration capability that traditional offline preparation achieves with manual evaporation steps.That said, offline sample preparation—including <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/article/5392">nitrogen-assisted evaporation</a> under controlled conditions, <a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/products/2407">liquid–liquid extraction</a>, and protein precipitation—retains significant advantages in flexibility, matrix handling, and the ability to process sample volumes that exceed online system capacity. The two approaches are increasingly complementary rather than competitive in well-designed analytical laboratories.<h4>High-Purity Solvents and Reference Materials</h4>As detection limits push further into the femtogram range and regulatory methods demand demonstrable blank performance, the quality of analytical consumables—mobile phase solvents, derivatization reagents, reference standards—has moved from background consideration to front-of-mind. Method validation in regulated environments now routinely requires vendor certification of solvent purity at a level that directly interfaces with instrument performance.<h3>The Ever-Present Need for Sample Evaporation</h3>As LC–MS/MS methods push detection limits lower, the analytical burden shifts increasingly upstream. The quality of the concentration, cleanup, and reconstitution steps preceding injection determines whether the instrument’s theoretical sensitivity is achievable in practice.Several specific developments are particularly relevant:<ul><li>ADC and gene therapy characterization workflows require gentle, low-temperature evaporation that preserves protein structure and prevents aggregation prior to LC–MS/MS. Nitrogen evaporation under controlled conditions is the preferred approach.</li><li>PFAS trace analysis demands evaporation systems constructed from PFAS-inert materials, with rigorous attention to avoiding fluoropolymer surfaces throughout the sample path.</li><li>High-throughput pharmaceutical QC driven by reshoring demands parallel processing capability—multi-position evaporators that maintain consistent flow and temperature across all positions simultaneously.</li><li>Multi-omics and metabolomics workflows generate large sample batches that benefit from automated, walk-away evaporation with programmable endpoints to ensure reproducible final volumes across a cohort.</li></ul>Tandem chromatography–mass spectrometry is not merely growing; it is becoming structurally embedded in the analytical workflows of every major regulated industry. The convergence of biopharma complexity, PFAS regulatory mandates, AI-enabled data analysis, and pharmaceutical reshoring is creating a multi-year demand cycle that will require laboratories to invest not only in instruments, but in the entire sample preparation ecosystem that makes those instruments perform.For analytical chemists, the practical takeaway is this: as mass spectrometry sensitivity continues to advance, the sample preparation step becomes the binding constraint on method performance. Whether you are developing a new PFAS method to meet EPA 1633, characterizing an ADC’s drug-to-antibody ratio, or running a 500-sample metabolomics cohort overnight, the reliability and cleanliness of your concentration and cleanup workflow determines the quality of every data point that follows.&nbsp;

The Continued Rise of Tandem Chromatography–Mass Spectrometry

<h3>A Practical Guide to Getting the Most from Syringe Filters: Tips, Tricks, and Common Pitfalls</h3>Syringe filters play a crucial role in chromatography and many other laboratory applications by removing particulate matter before analysis. Proper sample filtration helps protect analytical instruments, extends column lifetime, and improves data quality. However, selecting an unsuitable filter—or using one incorrectly—can introduce contamination, reduce filtration efficiency, or even compromise analytical results. The following recommendations will help you avoid common mistakes and ensure reliable filtration every time.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/KNAUER_Avoiding_Common_Syringe_Filter_Mistakes_3_150e8c1c2b.webp" alt="KNAUER: Avoiding Common Syringe Filter Mistakes" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_KNAUER_Avoiding_Common_Syringe_Filter_Mistakes_3_150e8c1c2b.webp 133w," sizes="100vw" width="1276" height="1496"><h4>1. Improper Filter Handling</h4>Using excessive force during filtration or attempting to reuse disposable syringe filters can damage the membrane and increase the risk of sample contamination.<ul><li>Solution: Apply slow, even pressure throughout the filtration process and always dispose of single-use filters after one use. If the flow rate decreases noticeably, replace the filter instead of applying additional force.</li></ul><h4>2. Selecting an Inappropriate Pore Size</h4>Using the wrong pore size may either fail to remove unwanted particles or cause the membrane to clog prematurely, reducing filtration efficiency.<ul><li>Solution: A 0.45 µm membrane is generally suitable for routine particulate removal, while a 0.22 µm membrane is recommended for finer filtration and bacterial removal. Samples with higher viscosity may require a pre-filter to prevent rapid clogging. It is also important to consider the intended analytical technique. For example, 0.22 µm filters are typically preferred for UHPLC and LC-MS applications, whereas 0.45 µm filters are often sufficient for conventional HPLC analyses.</li></ul><h4>3. Choosing the Wrong Membrane Material</h4>Different membrane materials exhibit different chemical resistance. Using an incompatible membrane may lead to degradation of the filter, sample contamination, or complete filtration failure.<ul><li>Solution: Always verify solvent compatibility before filtration. PTFE membranes are an excellent choice for organic solvents, while PES and nylon membranes are better suited to aqueous samples. If compatibility is uncertain, perform a small-scale trial before filtering valuable samples.</li><li>Pro Tip: For additional guidance, see our blog article "How to Choose the Right Membrane for your Syringe Filter", which provides a detailed comparison of membrane materials and their recommended applications.</li></ul><img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/KNAUER_Avoiding_Common_Syringe_Filter_Mistakes_2_e47021fb11.jpg" alt="KNAUER Sepapure® Syringe Filters are available with multiple membrane materials, each identified by a dedicated color code for quick and reliable selection." srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_KNAUER_Avoiding_Common_Syringe_Filter_Mistakes_2_e47021fb11.jpg 245w," sizes="100vw" width="1580" height="902"><h4>4. Ignoring Filter Capacity</h4>Using a filter with insufficient capacity can result in rapid membrane blockage, increasing filtration time and reducing laboratory productivity.<ul><li>Solution: When filtering larger sample volumes, choose high-capacity syringe filters or introduce a pre-filtration step. Never force liquid through a clogged membrane, as doing so may damage the filter and negatively affect sample quality.</li></ul><h4>5. Overlooking Sample Adsorption</h4>Certain membrane materials may adsorb analytes of interest, leading to lower recoveries and potentially affecting quantitative results.<ul><li>Solution: For protein samples or other adsorption-sensitive analytes, select membranes with low binding characteristics, such as nylon or glass fiber, whenever appropriate. Performing a small recovery test before routine analysis can help identify potential analyte losses.</li></ul><h4>6. Failing to Optimize Filtration Performance</h4>Slow filtration is more than just an inconvenience—it often indicates that the filtration conditions are not optimal.<ul><li>Solution: If filtration becomes unusually slow, investigate possible causes such as membrane clogging, excessive sample viscosity, or an unnecessarily small pore size. Depending on the sample, dilution or sequential filtration using progressively finer filters may significantly improve performance.</li></ul><h4>Final Thoughts</h4>Selecting the appropriate syringe filter is a straightforward process, but overlooking small details can have a significant impact on analytical performance. Choosing the correct membrane material, pore size, and filtration strategy helps improve laboratory efficiency, protects chromatography systems and columns, and contributes to accurate, reproducible analytical results.With the right syringe filter and proper filtration technique, you can minimize sample preparation problems and maximize confidence in every analysis.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/KNAUER_Avoiding_Common_Syringe_Filter_Mistakes_4_983a15e289.jpg" alt="KNAUER: Sepapure® Syringe Filter Selection" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_KNAUER_Avoiding_Common_Syringe_Filter_Mistakes_4_983a15e289.jpg 245w," sizes="100vw" width="1160" height="627">Happy filtering!

Modern biopharma pipelines are rapidly expanding beyond conventional monoclonal antibodies into multi‑specific formats and bioconjugates such as antibody–drug conjugates (ADCs) and antibody–oligonucleotide conjugates (AOCs). While these modalities unlock new therapeutic possibilities, their structural complexity significantly increases analytical demands. Molecular assembly, chain pairing, size, charge, and hydrophobic heterogeneity, post-translational modifications, and stability can all vary in subtle yet clinically meaningful ways. &nbsp;In this webinar, we present a practical, end‑to‑end characterization framework that connects LC-based strategies across structural levels—intact, subunit, and peptide—and shows how orthogonal separations support confident decisions from development through QC transfer. Topics include approaches to verify structural integrity, reveal mispaired or incorrectly assembled species, monitor size variants and aggregation, assign charge variants, and apply fit‑for‑purpose workflows to conjugated antibodies where additional heterogeneity must be controlled.Attendees will leave with a clear “analytical toolbox” perspective—understanding which techniques to apply, what questions each method answers, and how to assemble robust characterization strategies for emerging antibody modalities.<h4>What you'll learn</h4><ul><li>How multispecific formats and conjugates change analytical strategy vs. traditional mAbs</li><li>How LC separates and quantifies variants, while LC–MS enables molecular confirmation</li><li>How to align intact, subunit, and peptide workflows to specific analytical questions</li><li>How conjugation introduces new heterogeneity—and how to manage it effectively (ADC/AOC)</li></ul><h4>Why attend?</h4>As antibody therapeutics evolve from conventional mAbs to multi‑specific architectures and bioconjugates (ADCs and AOCs), analytical teams face complexity—more variants, more heterogeneity, and a greater need for orthogonal evidence to support confident development and control strategies.In this webinar, we share a pragmatic characterization roadmap using LC-based methods across intact, subunit, and peptide‑mapping workflows—showing how each layer answers different questions, and how to assemble them into a cohesive package.<h4>Key takeaways include:</h4><ul><li>Selecting LC/LC‑MS approaches for size, charge, and hydrophobic variants,</li><li>Detecting mispaired or incorrectly assembled multi‑specific species</li><li>Handling the added complexity of conjugated antibodies (ADC/AOC) within fit‑for‑purpose workflows</li></ul>Ideal for scientists in analytical development, CMC, and QC supporting next‑generation antibody therapeutics.<h4>Who should attend?</h4>Analytical scientists in biopharma R&amp;D, process development, and QC working with advanced antibody modalities.You can select the language of the content in the top right corner of your screen.
