Analysis of organic micro-pollutants in the environment by multi-dimensional UHPLC and high resolution/accurate mass spectrometry
The application of high resolution, accurate mass (HRAM) mass spectrometry coupled with multidimensional chromatographic separations, bioaffinity isolation techniques, and online sample preparation methods to detect, identify, and quantify emerging contaminants (including endocrine disruptors, pharmaceuticals, and surfactants) in wastewater and drinking water. The overarching goal of Lee’s research is to gain an increased understanding of how emerging contaminants are transported, transformed and induce deleterious effects within aquatic ecosystems.
Polysorbate Quantification and Degradation Analysis via LC and Charged Aerosol Detection
April 9th 2025Scientists from ThermoFisher Scientific published a review article in the Journal of Chromatography A that provided an overview of HPLC analysis using charged aerosol detection can help with polysorbate quantification.
Analyzing Vitamin K1 Levels in Vegetables Eaten by Warfarin Patients Using HPLC UV–vis
April 9th 2025Research conducted by the Universitas Padjadjaran (Sumedang, Indonesia) focused on the measurement of vitamin K1 in various vegetables (specifically lettuce, cabbage, napa cabbage, and spinach) that were ingested by patients using warfarin. High performance liquid chromatography (HPLC) equipped with an ultraviolet detector set at 245 nm was used as the analytical technique.
Removing Double-Stranded RNA Impurities Using Chromatography
April 8th 2025Researchers from Agency for Science, Technology and Research in Singapore recently published a review article exploring how chromatography can be used to remove double-stranded RNA impurities during mRNA therapeutics production.
