High-field asymmetric waveform ion mobility spectrometry (FAIMS) based on ion wind pumping systems

The invention discloses a FAIMS based on ion wind pumps, which comprises an electrical system and an ion mobility tube, wherein the ion mobility tube comprises an ion source, a separation detection system and an ion wind pumping system; a tube body of the ion mobility tube is composed of two substrates which are plated with electrodes and connected tightly with supporting beams to form air flow channels, and the electrodes comprise separation electrodes, detection electrodes, discharge electrodes and traction electrodes; wherein the separation electrodes, the detection electrodes and airflow channels among the separation electrodes and the detection electrodes form the separation detection system, the discharge electrodes, and the traction electrodes and airflow channels among the discharge electrodes and the traction electrodes form the ion wind pumping system; and the ion source is arranged on the inner side of an air inlet end of the substrate. A gaseous sample enters the ion mobility tube under the drive
