Quantitative Analysis of Dried Bloodspot 17-Hydroxyprogesterone by ACQUITY UPLC-MS/MS for Clinical Research

6 May 2014

The developed LC-MS/MS method enables the rapid measurement of DBS 17-OHP with analytical sensitivity and reproducibility. The simple liquid-liquid extraction technique generated a clean sample extract. This familiar and well-understood sample preparation technique can be easily adopted into routine use in a clinical research laboratory.

ACQUITY UPLC System

Waters

Waters ACQUITY UPLC - Dramatic Improvements in Speed, Sensitivity and Resolution Whether you work in methods development or quality assurance, in drug discovery and development or testing for safety in food supplies, you seek a productivity edge. With the ACQUITY UPLC® System, now you can get more information in a single, short run than you've ever seen with HPLC. Waters ACQUITY UPLC System UltraPerformance LC® (UPLC®) technology starts with unique 1.7 μm small-particle chemistries. Chromatographers no longer need to choose between speed and resolution–with UPLC you get both. Instrument Designed for Chemistry; Chemistry Designed for the Instrument The ACQUITY UPLC System has been holistically designed to match the performance needs of our innovative column chemistries with robust hardware, easy-to-use software and specialized support services. Small, pressure-tolerant particles High-pressure fluidic modules Minimized system volume Negligible carryover Reduced cycle times Fast response detectors Integrated system software and diagnostics With UPLC you have the ability to work more efficiently with higher speed, sensitivity and resolution at a much wider range of linear velocities, flow rates and backpressures to obtain superior results. The Waters ACQUITY UPLC System's high-pressure fluidics optimizes flow rates to make the most of small particle technology. The ACQUITY UPLC System's sample-handling design is designed to ensure exceptionally low carryover and reduced cycle time. And when interfaced with the Sample Organizer, it increases unattended sample capacity by ten times. High-speed detectors, both optical and mass, contribute to increased sensitivity and help manage the heightened speed and resolution requirements of UPLC. ACQUITY UPLC Systems are easily controlled, diagnosed, and monitored via a graphical system console interface. The console offers: Quick and easy access to critical instrument parameters Simple system start-up, elegant system status monitoring and predictive performance indicators to ensure maximum productivity Data management capabilities that are supported by both MassLynx™ and Empower™ software The ACQUITY UPLC System is also supported by Intelligent Device Management technology with our Connections® INSIGHT™ service, providing instrument diagnostics.

Mass SpectrometryMass spectrometry (MS) is a powerful analytical technique used to identify and quantify molecules based on the mass-to-charge ratio of gas-phase ions. It provides detailed information about the structure, composition, and properties of compounds and is widely used across fields such as environmental monitoring, materials science, drug discovery and development, food and beverage testing, and wider chemical research. Key MS techniques include tandem mass spectrometry (MS/MS), liquid chromatography–mass spectrometry (LS-MS) and inductively coupled plasma (ICP-MS). Choosing from these wide range of techniques and technologies can be a daunting task, so keep up to date with scientific applications, performance expectations, and customer reviews here all in one place. Visit our product directory to receive quotes direct from the manufacturer. BiomarkersBiomarkers are biological markers which can be measured and evaluated to indicate a biological state. The use of biomarkers in research and diagnosis can indicate a normal or disease state or drug response of cells / tissues. Biomarkers include genetic markers, cell surface markers such as antigens, antibodies or receptors and secreted molecules such as cytokines. An assay system is required for identification of biomarkers. :Clinical ChemistryBiochemistry (or clinical chemistry) involves the analysis of bodily fluids using chemical tests. Techniques used include HPLC, chromatography, spectroscopy, mass spectrometry, immunochemical, electrophoresis, turbidometric / spectrophotometric assay, MRI and ISE analysis. Tests are often carried out on plasma or serum but urine (urinalysis) and fecal specimens are also processed.Clinical Mass SpectrometryMass spectrometry is emerging as a superior method of analysis over the longstanding, gold standard of immunoassay. Clinical mass spectrometry systems are increasingly accessible to medical laboratories and are capable of providing results with more speed and less expense than traditional methods. From simple mass spectrometers to IVDR class A compliant, highly sophisticated systems performing liquid chromatography tandem mass spectrometry (LC/MS/MS), find the latest product news, reviews and resources to make a purchasing decision for your laboratory.
