Gas sampling device for environment detection

Technical Field

The utility model relates to the technical field of gas sampling, in particular to a gas sampling device for environment detection.

Background

Gas sampling is the process of taking a sample of a pollutant in the atmosphere or a sample of contaminated air. There are two types of collection methods: one is to make a large amount of air pass through a liquid absorbent or a solid adsorbent to enrich pollutants with low concentration in the atmosphere, such as an air extraction method and a filter membrane method. Another type is to collect the air containing the contaminants with containers (glass bottles, plastic bags, etc.). The former measures the average concentration of the pollutants in the atmosphere within the sampling time; the latter measured instantaneous concentrations or average concentrations over a short period of time. The sampling mode is determined according to the purpose of sampling and the field situation. The sample should be representative. The sampling efficiency is high, the operation is simple and convenient, and the subsequent analysis and measurement are convenient to obtain reliable basic data of gas pollution.
