Abstract: The present invention discloses an asymmetric field ion mobility spectrometer. It comprises an ionization source, for generating ions; an electrode plate; a plurality of electrode filaments, arranged in opposite to and spaced apart from the electrode plate by an analysis gap, wherein a high voltage of electrical field is applied between the electrode plate and the electrode filaments to form an ion migration area, the electrode filaments used to collect the ions that do not pass through the ion migration area; and a collection electrode, disposed at a rear end of the ion migration area, and collecting the ions that have passed through the ion migration area. The present asymmetric field ion mobility spectrometer is capable of improving accuracy of identifying peak positions of the ions, reducing scanning time of DC voltage and types of compensation voltage, thereby increasing ion detection efficiency.

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.
