Embodiment Construction

[0010] In one aspect of the present invention, an ion mobility spectrometer with a solid-liquid gas sampling device is provided, which includes an ion migration tube and a sampling device. The ion transfer tube includes ionization zone 17, reaction zone 18, and migration zone 19 from left to right. The sampling device includes the upper cover 3 of the sampling device, the lower cover of the sampling device 2, the heater 24, the sampling paper 10, and the gas collection tube. twenty two. The ionization zone includes a photoionization source 1. The light surface emitted by the photoionization source 1 is perpendicular to the transverse axis of the ionization zone 17. A through hole is provided on the end face of the ionization zone 17 in the direction opposite to the Faraday disk 15, and the through hole covers the lower cover of the sampling device 2 The cavity is connected to the ionization zone 17, and the size is 1mm≤the diameter of the through hole≤5mm. Opposite gas outlets...

Abstract

Provided in the invention is an ion mobility spectrometer with a solid-liquid-gas sample injection device. The ion mobility spectrometer comprises a solid-liquid-gas sample injection device, a filtering device, an ionization source, a gas pump and an electrode. A sample injection device is arranged at the front end of an ionization area and used for collecting samples. Since solid samples, liquidsamples and gas samples can be collected respectively, the detection range is wider, and the adaptability to the detection environment is improved.

Description

Technical field [0001] It relates to a technology that uses ion mobility spectroscopy, which belongs to the technical field of safety detection, and specifically relates to an ion mobility spectrum capable of detecting various types of substances. Background technique [0002] The ion mobility spectrometer is composed of sampling part, ionization part, ion gate, migration area, collection area, data acquisition and processing, control and other parts. [0003] For the general use of single-type sampling technology, there are fewer types of detection, and the application environment is limited. It cannot meet the detection of multiple types of multi-form substances at one time. The present invention aims to solve the above problems. Summary of the invention [0004] The object of the present invention is to provide a method capable of detecting various types of substances. An ion mobility spectrometer with a solid-liquid-gas sampling device is proposed. It includes an ion migration...
