8 kinds of sulfur organic compounds in stationary pollution source exhaust gas methyl mercaptan
8 kinds of sulfur organic compounds in stationary pollution source exhaust gas methyl mercaptan Details:


Name: Capillary Column
Stationary phase: 100% dimethyl polysiloxane stationary solution
Specification: 60m*0.32mm*1.04um
Model: SE-30
Application: HJ 1078-2019 Fixed pollution source waste gas, methyl mercaptan and other 8 sulfur-containing organic compounds, air bag sampling-preconcentration/gas chromatography-mass spectrometry

In order to implement the "Environmental Protection Law of the People's Republic of China" and "The Air Pollution Prevention Law of the People's Republic of China", protect the ecological environment, protect human health, and standardize the determination method of sulfur-containing organic compounds in the exhaust gas of fixed pollution sources, this standard is formulated. This standard specifies the air bag sampling-pre-concentration/gas chromatography-mass spectrometry method for the determination of 8 sulfur-containing organic compounds such as methyl mercaptan in the exhaust gas of stationary sources. Appendix A of this standard is a normative appendix, and Appendix B and Appendix C are informative appendices. This standard is issued for the first time.

This standard specifies the air bag sampling-pre-concentration/gas chromatography-mass spectrometry method for determining 8 sulfur-containing organic compounds such as methyl mercaptan in the exhaust gas of stationary sources. This standard is applicable to the determination of 8 sulfur-containing organic compounds in exhaust gas from stationary pollution sources, including methyl mercaptan, ethyl mercaptan, methyl sulfide, methyl ethyl sulfide, carbon disulfide, ethyl sulfide, dimethyl disulfide, and thiophene. When the sampling volume is 50.0 ml, the detection limit of the method for the determination of sulfur-containing organic compounds in this standard is 0.01～0.02 mg/m3, and the lower limit of determination is 0.04～0.08 mg/m3. See Appendix A for details.

The waste gas from a fixed pollution source is collected with an air bag, concentrated by a cold trap and thermally analyzed, and then separated into a gas chromatograph for detection by a mass detector. It is qualitatively compared with the mass spectrum and retention time of the standard material, and quantified by the internal standard method.
