Background
Atmospheric sampling is an important step in atmospheric environmental monitoring, and has a great relationship with reliability of monitoring data. Methods for collecting atmospheric samples are mainly classified into two types, namely, a method for making a large amount of air pass through a liquid absorbent or a solid absorbent so as to absorb or block pollutants, and a method for enriching the pollutants with lower concentration in the original atmosphere, such as an air extraction method and a filter membrane method. The result of this type of measurement is the average concentration of contaminants in the atmosphere over the sampling time. The other is to collect the air containing the contaminants with a container (glass bottle, plastic bag, rubber bladder, syringe, etc.). Such a method is suitable for the following cases: the concentration of pollutants in the atmosphere is higher or the sensitivity of the measuring method is higher; contaminant gases and vapors that are not readily absorbed by the liquid absorbent or by the solid absorbent.
