Ion mobility spectrometry (IMS) is an analytical technique used initially for the detection of trace quantities of gaseous organic compounds at atmospheric pressure. In conventional ion mobility spectrometry, an ionized sample enters a drift tube that contains an electric field and carrier buffer gas. As ions move through the matrix, they are separated according to their size, shape, and charge. Differential migration time through the tube can be used to identify analytes.
The SelexION® Technology is an effective differential ion mobility separation tool for improving data quality in the quantitation and characterization of challenging samples requiring advanced analytical selectivity.
