Problems solved by technology

For a separate GC, headspace sampling is generally used, which saves complicated sample pretreatment (suitable for rapid detection), but headspace sampling still needs to "destructively" obtain a certain amount of samples, so it is not suitable On-site quick detection of trace gas without unpacking

Abstract

The invention discloses detection equipment and a detection method. The detection equipment comprises a sampling device, a pretreatment sampling device and a sample analysis device, wherein the sampling device is used for collecting to-be-detected samples; the pretreatment sampling device is used for pretreating samples from the sampling devices; the sample analysis device is used for separating pretreated samples from the pretreatment sampling device and analyzing separated samples. According to the detection equipment disclosed by the invention, miniaturization is realized, gas-phase matters or particulate matters can be quickly and accurately detected under an unpacking situation, the accuracy is high, and the detection equipment is suitable for safety inspection of airports, ports, subway stations and the like.

Description

[0001] This case is a divisional application submitted on December 31, 2014 with the application number 201410855312.0 and the title of the invention "Detection Equipment and Detection Method" technical field [0002] The invention relates to the technical field of safety detection, in particular to a detection device and a detection method. Background technique [0003] Ion mobility spectrometer (IMS) is one of the mainstream trace detection equipment in the world at present. IMS technology mainly separates and identifies samples based on the difference in the mobility of different ions under the action of a weak electric field. It has a simple structure and high sensitivity. , fast analysis speed and reliable results, etc. It can quickly detect drugs, explosives, poisonous gas and biochemical gases online, and is widely used in military (chemical warfare agent monitoring), civil (anti-terrorism, anti-drug, etc.) and many other fields. It plays a huge role in national secur...
