Meeting EU Drinking Water Standards: The Critical Role of Sample Prep in Trace Contaminant Analysis

Although modern agriculture needs to be based on accurate real-time data on soil, plant, and environmental conditions, affordable, sufficiently sensitive, and robust monitoring devices for this purpose are currently missing. According to scientists, low-cost sensors based on new smart materials and printing technologies offer a suitable solution. The results of multidisciplinary research thus far and proposals for the development of these devices have been presented by researchers from Czechia, Great Britain, Spain, and the USA in a review article in the prestigious journal <a target="_blank" rel="noopener noreferrer" href="https://www.nature.com/articles/s41467-026-68778-6#Abs1">Nature Communications</a>.“Sensor technologies for monitoring plant health are still in their infancy. Only simple sensors capable of monitoring basic parameters such as pH, soil moisture, or temperature are commonly available on the market. However, if farmers are to face current challenges, including climate change, and ensure sufficient food for humanity, they need much more effective tools that will enable them to monitor, for example, various pathogens, including bacteria and fungi. In our opinion, a suitable solution is a combination of new smart materials and printing for the production of inexpensive, durable, and scalable materials,” said the article’s first author, David Panáček from CATRIN, who worked on the study during his internship at Imperial College London.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/CATRIN_Soucasne_senzory_nestaci_Vedci_navrhuji_novou_cestu_ke_sledovani_zdravi_rostlin_b4014952a3.jpg" alt="CATRIN: David Panáček" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_CATRIN_Soucasne_senzory_nestaci_Vedci_navrhuji_novou_cestu_ke_sledovani_zdravi_rostlin_b4014952a3.jpg 208w," sizes="100vw" width="1536" height="1152">Sensors for monitoring plant health, for example, lag behind similar devices used in human medicine. According to the authors, advances in materials science, which will enable the development of scalable sensor technologies, play a key role in this potential shift. “Printing techniques, including inkjet printing, screen printing, aerosol printing, 3D printing, and direct laser writing, offer flexible ways to produce flexible sensors, large-area sensors, and sensors integrated directly into plants. The review article summarizes recent advances in printable low-dimensional materials for agricultural sensors, analyzes their physico-chemical properties in relation to sensor performance, and discusses key challenges and future opportunities requiring interdisciplinary integration,” said one of the corresponding authors, Michal Otyepka.The research brought together materials scientists, chemists, biologists, sensing experts, and printing technology specialists. Materials research and the use of graphene-based smart materials were led by scientists from CATRIN at Palacký University and VŠB-Technical University of Ostrava. Plant biologists from CATRIN contributed their knowledge of plant development, their responses to stress conditions, and the monitoring of their properties. Researchers from Imperial College London took care of the electronics, while representatives from<a target="_blank" rel="noopener noreferrer" href="https://lcms.labrulez.com/companies/36"> CEITEC – VUT</a> focused on printing technologies. The team also included leading experts in sensing from the Catalan Institute of Nanoscience and Nanotechnology in Barcelona, and Joseph Wang of the University of California San Diego, the “father of sensing and electrochemistry,” also contributed his extensive knowledge.“This is a groundbreaking study on this topic, which has managed to attract some truly big names in their respective fields. Last but not least, the study demonstrates that interdisciplinarity at CATRIN gives rise to completely new and promising research topics, such as plant sensing and its use for studying plant-environment interactions and smart agriculture,” added another corresponding author, Nuria De Diego.

Current sensors are not good enough. Scientists propose a new way to monitor plant health

In this episode of the Concentrating on Chromatography podcast, host David Oliva interviews Ainslie Chen about her cutting-edge research on hemoglobin variant testing using liquid chromatography-high resolution mass spectrometry (LC-HR-MS). Ainslie discusses her novel method for separating and identifying hemoglobin subunits with mass shifts less than 1 Da, overcoming critical limitations in conventional clinical assays.Hear firsthand how her team developed an LC-HR-MS workflow using a C4 reversed-phase column, tackled technical challenges (including why C18 columns fell short), and achieved unprecedented sensitivity for variant detection in both adult and neonatal samples. The conversation touches on the potential of mass spectrometry to revolutionize clinical diagnostics, the importance of reproducibility, barriers to adoption in routine labs, and how teamwork drives scientific innovation.Perfect for analytical chemists, clinical laboratorians, and anyone interested in the future of protein variant analysis, this episode also features Ainslie’s advice for early-career scientists and insights from her first ACS poster presentation.<h4>Key Highlights:</h4><ul><li>Motivation behind improving hemoglobinopathy testing &nbsp;</li><li>Technical advantages of LC-HR-MS over gene sequencing and CE &nbsp;</li><li>The crucial role of the C4 column in resolving challenging samples &nbsp;</li><li>Critical parameters for reproducible LC-HR-MS workflows &nbsp;</li><li>Barriers and outlook for clinical adoption of advanced mass spectrometry &nbsp;</li><li>The value of teamwork and mentorship in scientific research &nbsp;</li><li>Direct insights from recent ACS conference experiences</li></ul><h3>Video transcription</h3>In this interview, Ainslie Chen discusses her research on improving the detection and identification of hemoglobin variants using liquid chromatography coupled with high-resolution mass spectrometry (LC-HRMS). The work addresses limitations of conventional hemoglobinopathy testing, which often struggles to resolve very small mass differences between closely related hemoglobin subunits. Because even a single amino-acid substitution can significantly alter hemoglobin structure and function, high analytical resolution is essential for accurate diagnosis of conditions such as anemia and sickle cell disease.Chen explains why her team selected LC-HRMS over established clinical techniques like capillary electrophoresis and gene sequencing. While sequencing offers excellent accuracy, it is time-consuming, costly, and requires extensive sample preparation, making it impractical for routine clinical workflows. Capillary electrophoresis enables subunit separation but lacks the resolving power needed to distinguish variants differing by less than one Dalton. In contrast, high-resolution mass spectrometry provides both structural specificity and sensitivity, enabling confident identification of subtle hemoglobin variants with minimal sample preparation.A key methodological insight from the project was the use of a C4 reversed-phase LC column instead of the more common C18 column. Chen describes how the shorter carbon chain and larger pore size of C4 columns improved protein elution and reduced denaturation, leading to more reproducible separations. Critical parameters for reproducibility included consistent mobile-phase composition (0.1% formic acid in water and acetonitrile), controlled temperature (60 °C for LC, ~320 °C capillary temperature), and stable chromatographic conditions.Beyond hemoglobin analysis, Chen highlights the broader potential of high-resolution mass spectrometry in proteoform analysis and clinical diagnostics, including emerging applications in cancer detection. She acknowledges current barriers to clinical adoption—such as energy demands and instrument infrastructure—but points to advances like miniaturized mass spectrometers as promising steps toward wider use. The interview concludes with advice for young scientists: don’t hesitate to reach out to mentors, embrace collaboration, and view analytical chemistry as a versatile tool that bridges medicine, biology, environmental science, and beyond.<blockquote>This text has been automatically transcribed from a video presentation using AI technology.

Waters/Wyatt microDAWN™ Multi Angle Light Scattering (MALS) Detector

The microDAWN can be coupled to any UHPLC-SEC system to determine absolute molecular weights and sizes of polymers, peptides, or proteins directly, without resorting to column calibration or reference standards.

<h4>Overview</h4><h5>UHPLC-SEC System</h5>The microDAWN can be coupled to any UHPLC-SEC system to determine absolute molecular weights and sizes of polymers, peptides, or proteins directly, without resorting to column calibration or reference standards. The microDAWN produces minimal band broadening in order to maintain the narrow peaks typical of UHPLC, while meeting or exceeding the sensitivity of the miniDAWN™.<h4>Product Description</h4>The microDAWN MALS detector performs absolute characterization of macromolecules eluting from UHPLC, determining molar mass and size independently of retention time and molecular reference standards. This instrument offers superb sensitivity over a wide range of molar mass, size and concentrations. In most respects the microDAWN is similar to the well-established miniDAWN™, a workhorse MALS instrument used in hundreds of labs around the world for characterizing proteins and other molecules smaller than 50 nm in radius.Distinctly from the miniDAWN, the microDAWN is uniquely suitable for use in conjunction with UHPLC Size Exclusion Chromatography (SEC-MALS) thanks to its small interdetector dispersion. In some cases it may be used with ion-exchange or other types of chromatography. Regardless of the specifics, the microDAWN produces minimal band broadening in order to maintain the narrow peaks typical of UHPLC.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_micro_DAWN_MALS_HPLC_detektor_konfigurace_1_4e888650cf.jpg" alt="Waters microDAWN™ Multi Angle Light Scattering (MALS) Instrument: Experimental setup" srcset="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/thumbnail_Waters_micro_DAWN_MALS_HPLC_detektor_konfigurace_1_4e888650cf.jpg 229w," sizes="100vw" width="894" height="609"><ul><li>Mw&nbsp; from 200 Da to 10 MDa</li><li>Sensitivity: 1.0 µg/mL BSA (66.4 kDa) in PBS; 50 ng/mL 100 kDa polystyrene in THF.</li><li>Rg &nbsp;from 10 to 50 nm</li><li>Ultra-stable laser</li></ul>The microDAWN and its companion microOptilab™ Refractive Index Detector interface to most standard UHPLC systems.

Waters/Wyatt ViscoStar HPLC viscometer

Waters ViscoStar is a highly sensitive, on-line differential viscometer used in conjunction with SEC-MALS-IV to determine the size and conformation of all types of biopolymers, synthetic polymers and even proteins and peptides.

<h4>Highly Sensitive</h4>A highly sensitive, on-line differential viscometer used in conjunction with SEC-MALS-IV to determine the size and conformation of all types of biopolymers, synthetic polymers and even proteins and peptides.<h4>Multiple Novel Technologies</h4>The ViscoStar incorporates multiple novel technologies to provide the highest sensitivity, stability and solvent compatibility of any available viscometer for GPC. Its ease-of-use and serviceability make it the perfect companion for Wyatt's DAWN™ light scattering and Optilab™ refractive index detectors.<h4>Another path to polymer and protein characterization: SEC-MALS-IV</h4>When coupled with size-exclusion chromatography and a concentration detector such as the Optilab™ , the ViscoStar derives the intrinsic viscosity (IV) of polymers. An inherently valuable physico-chemical property in itself, IV is best utilized together with molar mass information from multi-angle light scattering (SEC-MALS-IV) to derive the hydrodynamic radius, conformation, and branching ratio of a macromolecule in solution.<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_Visco_Star_pump_pulse_suppression_with_inset_e8c2fbfc18.jpg" alt="Waters ViscoStar: Patented pulse compensation technology in the ViscoStar eliminates pump fluctuations.

While universal calibration overcomes some of the problematic issues associated with column calibration by reference molecules, it does not account for non-ideal column behavior caused by chemical solute-column interactions or hyperbranching.Universal calibration is particularly-well suited to replace MALS for:<ul><li>Strongly fluorescent polymers, in particular those not adequately addressed by a DAWN™ with long-wavelength (785 nm) laser or a standard DAWN (685 nm) with fluorescence-blocking filters.</li><li>Weakly-scattering polymer/solvent systems with very low dn/dc values</li></ul>The Mark-Houwink-Sakurada relationship makes use of empirical relationships between intrinsic viscosity and molar mass, specific to each polymer and solvent, to estimate molar mass from SEC-IV measurements. Of course, the best way to determine MHS coefficients is to measure them using SEC-MALS-IV and ASTRA™!<img src="https://storage.googleapis.com/labrulez-bucket-strapi-h3hsga3/Waters_Visco_Star_v3_protein_rh_measurements_0951d3769a.jpg" alt="Waters ViscoStar: Three IgG proteins with similar MWs eluted at different elution volumes.

Waters/Wyatt microOptilab On-line Differential Refractometer

The Waters microOptilab brings the universal detection capabilities, unsurpassed concentration range, and superb sensitivity and linearity

<h4>Independent of Chromaphores</h4>Independent of chromaphores or fluorophores, differential Refractive Index (dRI) detectors measure concentrations of all types of samples in almost all solvents. The microOptilab brings the universal detection capabilities, unsurpassed concentration range, and superb sensitivity and linearity – familiar from the Optilab™ – to the domain of UHPLC.<h4>SEC-MALS with UHPLC</h4>Like standard SEC, UHPLC-SEC analysis relying on column calibration with molecular standards is unreliable when the standards do not accurately reflect your samples in terms of conformation, non-ideal (e.g., hydrophobic) column interactions or reversible association. SEC-MALS employs a microDAWN™ MALS detector downstream of the SEC column and UV detector, to determine molar mass / molecular weight distributions of macromolecules independently of column calibration.Refractive index detection is an important component of any SEC-MALS system, and necessary for analyzing conjugated proteins or polymers devoid of chromaphores. The microOptilab connects with the microDAWN MALS detector for a complete UHP-SEC-MALS setup that transfers the many benefits of SEC-MALS analysis to the realm of UHPLC.<h5>Key benefits</h5><ul><li>Very low band broadening, &lt; 4 µL, to maintain the resolution of very narrow UHPLC peaks</li><li>Extraordinary dRI measurement range, -4.7 x 10 -3 &nbsp;to +4.7 x 10 -3 &nbsp;RIU (comparable to 25 mg/mL protein in PBS)</li><li>Highly sensitive, ± 1.5 x 10 -9 &nbsp;RIU across the entire measurement range</li><li>Measures solvent refractive index, require for MALS calculations</li><li>Measures at the same wavelength as the MALS detector, for maximum accuracy in MALS calculations</li><li>Temperature range 4 °C to 65 °C for proteins and polymers that require a range of temperatures</li><li>High-resolution, touch-screen front panel displays data graphs and instrument diagnostics, even with the host computer turned off</li></ul><h5>Unparalleled features</h5><ul><li>Considering the extremely small peak volumes of UHPLC, band broadening in the microOptilab is kept to the absolute minimum, at less than 4 µL, as compared to 20 - 40 µL or more for standard RI detectors. As a result, the superior resolution from UHPLC columns and instruments will not be compromised with the microOptilab RI detector.</li><li>Even though the microOptilab offers a dRI measurement range orders of magnitude beyond that of other UHPLC dRI detectors, unlike other detectors there are no range or gain settings in the microOptilab. The full range of instrument detection is always present, and the full sensitivity exists over the entire range. The small flow cell and proprietary temperature regulation enable stable RI baselines and signals which further enhance the detector's sensitivity.</li><li>Unlike all other dRI detectors, the microOptilab also measures absolute refractive index in order to determine solvent RI, necessary in light scattering calculations and useful in assessing the accuracy of mixing of solvent gradients.</li><li>The microOptilab can be operated below ambient temperatures as easily as above ambient.
