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 used for collecting a sample to be detected, a preprocessing sample injection device used for preprocessing the sample from the sampling device, and a sample analysis device used for separating the preprocessed sample from the preprocessing sample injection device and analyzing the separated sample. The detection equipment is miniaturized, can quickly and accurately detect gas-phase matters or particulate matters without unpacking, and is high in accuracy and suitable for security check of airports, ports, metro stations and the like.

Description

technical field [0001] The invention relates to the technical field of safety detection, in particular to a detection device and a detection method. Background technique [0002] 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 security, maintaining social stability, strengthening national defense, and maintaining the national economy and people's livelihood. However, when a single IMS is used to detect a complex mixture of...
