1 Introduction 
 XQC-15E air sampler is used to collect atmospheric gases in the environment and commonly used instrument shop floor. It is widely used in atmospheric environmental monitoring, health and epidemic prevention, labor protection, scientific research units to use, but also with supporting the use of the equipment. Gas analysis on samples to understand the environment is the extent of harmful gas pollution, pollution to the relevant competent departments of the actual situation, to take measures to safeguard the people have a healthy living environment. 
 The instrument is compact, stable performance, small size, light weight, easy to carry, is currently a small portable air sampler in the ideal instrument. Exchange different sampling load, can capture toxic gases, dust and activated carbon can also be collected sample tubes, etc., for multi-function atmospheric environmental monitoring, can be done with one machine.
