Abstract:A hydrophilic interaction liquid chromatography (HILIC)-MS/MS profiling method was developed for the efficient separation and quantification of small polar molecules, mostly primary metabolites. The method was based on an ultrahigh performance liquid chromatography (UHPLC) separation system coupled with ESI mass spectrometry on a triple quadrupole mass spectrometer, operating in both positive and negative ionisation mode using rapid polarity switching. With the developed method quantitation of 135 compounds be…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute of Drug Abuse of the National Institutes of Health.
