Methods and systems are provided for detecting analytes in a gas phase sample. An ion mobility spectrometer is provided for detecting analytes having an excess amount of dopant in its separation region. In an embodiment, the dopant is added directly to the separation region, such as with a drift gas...http://www.google.es/patents/US7985949?utm_source=gb-gplus-sharePatente US7985949 - Detection of analytes using ion mobility spectrometry
