Description

technical field

[0001] The invention relates to a detection device for volatile organic compounds, in particular to an ionization adsorption enrichment device. Background technique

[0002] The development of modern industry is very rapid and its application is very wide. While bringing convenience to human beings, its side effects bring great harm to human beings, such as the environmental pollution caused by volatile organic compounds (VOCs) has become very serious. VOCs permeate all aspects of human life, from chemical plant emissions, leakage from transportation and storage, dioxins from waste incineration, and pollution released from materials in home decoration. Although volatile organic pollutants are trace amounts, and their concentrations are in the order of ppm or less than in the order of ppm or as low as in the order of ppb, their impact on humans is very large. It is believed that more than 60% of human blood diseases are caused by such compounds Yes, more seri...
