Striving to Validate Nutraceuticals

Many multi-column gas chromatography systems use two-position multi-port switching valves, which can suffer from delays in valve switching. Shimadzu researchers aimed to create a new sampling and switching module for these systems.

Saba Aslani from the University of Texas at Arlington spoke to LCGC International about a collaborative project with Northwestern University, the University of Hong Kong, and BioTools, Inc., investigating mirror-image cyclodextrins using ultra-high performance liquid chromatography–tandem mass spectrometry (UHPLC–MS/MS) and vibrational circular dichroism (VCD).

Separating stereoisomers is an extensively researched and challenging process, with approved substances being rare. A new SFC-based system was made to possibly ease some aspects of these procedures.
