A Novel Strategy to Screen and Profile Steviol Glycosides of Natural Sweeteners in Food Using ionKey/MS Ion Mobility Mass Spectrometry
28 July 2015
In this application note, we illustrate the selectivity of collision cross section (CCS) measurements used in combination with other recent MS technology enhancements for profiling complex mixtures. A combination of high resolution mass spectrometry and high efficiency ion mobility based measurements and separations is used. Ion mobility is a rapid orthogonal gas separation phase technique that allows another dimension of separation to be obtained within an LC timeframe. Compounds can be differentiated based on size, shape, and charge.
