Abstract

The invention relates to a dopant gas generating device. The dopant gas generating device is utilized for providing reaction gas for an ion mobility spectrometer. The dopant gas generating device comprises a doping tank, a gas inlet pipe, wherein an inlet end of the gas inlet pipe is connected to an upstream side of a gas carrying passage and an outlet end of the gas inlet pipe is connected to the doping tank, an gas outlet pipe, wherein an inlet end of the gas outlet pipe is connected to the doping tank and an outlet end of the gas outlet pipe is connected to a downstream side of the gas carrying passage, a dopant gas generating unit, wherein the dopant gas generating unit is utilized for releasing dopant gas and is arranged in the doping tank, and a bottom cover, wherein the bottom cover is removably connected to a lower end of the doping tank and is provided with a support for fixing the dopant gas generating unit. The dopant gas generating unit for releasing dopant gas is arranged in the doping tank and thus the dopant gas generating device is suitable for a solid doping agent and a liquid doping agent.

Description

[0001] This application is a divisional application of a patent application (application date June 30, 2009, application number 200910088628.0, title of the invention is "dopant gas generating device"). technical field [0002] The invention relates to a doping gas generating device, which can use both solid dopant and liquid dopant. More specifically, the present invention relates to a device for generating dopant gas with stable concentration and adjustable concentration for ion mobility spectrometer, so as to improve the detection performance of ion mobility spectrometer IMS instrument. Background technique [0003] Ion mobility spectrometry (IMS) is a rapid, sensitive, and portable on-site detection technique. The technology has begun to be used in military and security inspection agencies to detect chemical poisons, explosives and drugs. When the ion mobility spectrometer detects contraband, in order to eliminate interference and improve the detection sensitivity of th...
