Abstract: An ion mobility spectrometer system is disclosed. In one aspect, the system includes a gas chromatograph, first and second ion mobility spectrometers, and a sample feed device that feeds a sample from the gas chromatograph to the first and second ion mobility spectrometers. The sample feed device includes an inner chamber, first and second sample outlets for outputting the sample from the gas chromatograph to the first and second ion mobility spectrometers, respectively, and a gas inlet for inputting a gas into the sample feed device. The system detects and identifies molecules at improved resolution and enhanced molecule information. The system detects positive and negative ions, interrelates positive-mode and negative-mode spectrums, and separates substances.
