Zusammenfassung:	Method and systems for managing clear-down are provided. The method can include generating a clear-down trigger associated with an ion mobility spectrometer and operating the ion mobility spectrometer in fast clear-down mode in response to the clear-down trigger. Methods and systems can further provide that where the ion mobility spectrometer operates in fast-switching mode, the ion mobility spectrometer alternating a plurality of times between operation according to a positive ion mode and operation according to a negative ion mode, and further operating according to the positive ion mode for less than about 1 second before switching to the operation according to the negative ion mode, and operating according to the negative ion mode for less than about 1 second before switching to the operation according to the positive ion mode.
