Waste gas from stationary pollution sources - Determination of volatile organic compounds
Determination of volatile organic compounds in waste gas from stationary pollution sources Details:

Name: capillary column
Stationary phase: 6% nitrile propylphenyl 94% dimethylpolysiloxane,
Specifications: 60m*0.32mm*1.8um
Model: HH-624
Application: DB37T 4433-2021 Waste gas from stationary pollution sources-Determination of volatile organic compounds-Gas bag vacuum bottle sampling-Gas chromatography-mass spectrometry

In order to strengthen the monitoring of volatile organic compound emissions and promote the improvement of ambient air quality, the Shandong Provincial Department of Ecology and Environment organized the compilation of the local ecological environment standard "Determination of volatile organic compounds in stationary pollution source exhaust gas vacuum bottle sampling-thermal desorption gas chromatography-mass spectrometry", And on May 12, a draft for comments was released to solicit suggestions from all parties.
The monitoring of VOCs in my country started late, especially for the monitoring of waste gas from fixed pollution sources. The monitoring specifications are few and the pertinence is not strong. There are only 5 monitoring specifications for volatile organic compounds in waste gas from fixed pollution sources, and there are few monitoring items and universal application. Secondly, the research on the pollution status of VOCs emitted by fixed pollution sources in my country is in its infancy, and the types, concentration levels, etc. of key VOCs in different industries are unclear. significant.
