Abstract
An apparatus and method of analyzing ions is described in which a Differential Mobility Analyzer (DMA) is combined with an analysis device. The DMS can be operated in first and second modes of operation to produce a plurality of ions that are sampled and analyzed by the analysis device. In the first mode of operation the DMA is configured to enable ion mobility separation and the analysis device samples and analyzes ions having ion mobility in a certain range of ion mobility and in the second mode of operation the DMA is configured to disable ion mobility separation and the analysis device samples and analyzes ions without discrimination based on ion mobility.
