8 kinds of sulfur-containing compounds of methyl mercaptan in the exhaust gas of stationary pollution source Details:

Name: Capillary Column
Stationary phase: 100% dimethyl polysiloxane stationary solution
Specification: 60m*0.32mm*1.04um
Model: HH-1
Application: Determination of 8 kinds of sulfur-containing organic compounds such as methyl mercaptan, waste gas from stationary sources

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 pollution sources.



  This standard is applicable to the determination of 8 sulfur-containing organic compounds in fixed pollution source exhaust gas: methyl mercaptan, ethyl mercaptan, methyl sulfide, methyl ethyl sulfide, carbon disulfide, ethyl sulfide, dimethyl disulfide, and thiophene.



  When the sampling volume is 50.0ml, the detection limit of sulfur-containing organic compounds in this standard is 0.01～0.02mg/m3, and the lower limit of determination is 0.04～0.08mg/m3. See Appendix A for details.
