Scientists from the Lunan Pharmaceutical Group explored the use of UHPLC-MS/MS to test the effects of Shouhui Tongbian capsules (SHTBs) on slow transit constipation (STC).
Why is Open-Access Hyphenation Important for Chromatographers?
October 4th 2023At HPLC 2023, John Langley, a professor at the University of Southampton in Southampton, UK, presented a talk called "(R)evolution of Hyphenations, Through Open-Access RP-HPLC–MS, Open-Access UHPSFC–MS and 2D-LC–IMS-MS in Academia". He spoke with LCGC on the importance of open-access hyphenation, and how to implement it in your research.
Scientists used supercritical fluid chromatography (SFC) and ultrahigh-pressure liquid chromatography (UHPLC)—both coupled with high-resolution mass spectrometry (HRMS)—to analyze various types of chlorinated paraffins (CPs) in fish oil-based dietary supplements.
Multitargeted Internal Calibration Using LC–MS Quantifies Chronic Kidney Disease-Linked Metabolites
September 30th 2023Researchers have developed a multitargeted internal calibration method for precise quantification of chronic kidney disease (CKD)-related endogenous metabolites using liquid chromatography–mass spectrometry (LC–MS).
Review of Portable X-ray Fluorescence in Analysis Applications for Solid and Liquid Food Samples
September 10th 2023This report not only focused on the different types of portable X-ray fluorescence (pXRF) spectrometers available, but also their capacities for limits of detection and quantification (LOD and LOQ, respectively), linearity, and calibration strategies.
