摘要: The use of CO2 as a massive and polarizable drift gas is shown to greatly improve peak-to-peak resolution (Rp-p), compared with N2, for the separation disaccharides in Synapt G2 traveling wave ion mobility cell. Near or baseline Rp-p was achieved three pairs sodiated molecules disaccharide isomers, that is, cellobiose sucrose (Rp-p = 0.76), maltose (Rp-p = 1.04), lactose (Rp-p = 0.74). Ion mass spectrometry using offers therefore an attractive alternative fast efficient isomeric disaccharides. Copyright © 2012 John Wiley & Sons, Ltd.
