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.

Abstract: The present invention provides a corona discharge device, comprising a first electrode including: a first substantially cylindrical inner chamber portion and a second substantially conical inner chamber portion in communication with the first inner chamber portion, wherein the second inner chamber portion has a cross sectional area that gradually enlarges in a direction away from the first inner chamber portion. The present invention also provides an ion mobility spectrometer comprising: an ionization region; and the corona discharge device disposed in the ionization region. With the above construction and structure, the ion mobility spectrometer of the present invention has the advantages that extraction of ions is facilitated and a life time of the corona electrode is lengthened. In addition, the focusing and storing electrode is used to effectively shield interference of a corona discharge pulse, and to push and focus sample ions. A designed voltage control solution is used to achieve mobility differentiating of ions, while a corona pulse is shielded to prevent variation in an ion quantity due to the corona pulse, thereby achieving an effect of stabilizing mobility spectrum lines.
