IONIZATION DEVICE, MASS SPECTROMETER, ION MOBILITY SPECTROMETER, AND IONIZATION METHOD

摘要

The present invention relates to the field of mass and/or ion mobility spectrometers. Provided is an ionization device and a mass spectrometer and an ion mobility spectrometer having same. Further provided is an ionization method. A sampling probe of the ionization device of the present invention is able to actively and rapidly collect samples, while a sampling device and a thermal desorption device are combined into one, simplifying and compacting the sampling device. An ionization part is provided downstream of the sampling and desorption part, ensuring that the sampling probe will not interfere with a flow field or an electric field between the ionization part and the analysis assembly inlet, thus ensuring repeatability of the device signal and flexibility of analysis.
