Abstract

In an ion mobility spectrometer, ions are generated, mobility-separated and deposited on a receiver, preferably at spatially separated positions by soft landing or crash landing techniques. The ion mobility spectrometer can be a stand-alone instrument or part of a hybrid analysis instrument. To analyze the deposited ions, the receiver is removed from the vacuum system of the ion mobility spectrometer and introduced into an analytical instrument. Various physical, chemical, and biological analysis techniques and instrumentation can be used, such as mass spectrometry or surface analytical techniques, by selecting a special receiver suitable for the desired analytical technique.
