HJ 604-2017 Ambient Air Determination of Total Hydrocarbons, Methane and Non-Methane Total Hydrocarbons Direct Injection-Gas Chromatography
1 Scope of application
      This standard specifies the direct injection-gas chromatography method for the determination of total hydrocarbons, methane and non-methane total hydrocarbons in ambient air.
      This standard applies to the determination of total hydrocarbons, methane and non-methane total hydrocarbons in ambient air, and also applies to the determination of total hydrocarbons, methane and non-methane total hydrocarbons in the air at monitoring points of fugitive emissions from pollution sources.

When the injection volume is 1.0ml, the detection limit of this standard for the determination of total hydrocarbons and methane is 0.06 mg/m3 (calculated as methane), and the lower limit of detection is 0.24 mg/m3 (calculated as methane); non-methane total hydrocarbons The detection limit is 0.07 mg/m3 (calculated by carbon), and the lower limit of determination is 0.28 mg/m3 (calculated by carbon).

2 Normative references

3 Terms and Definitions

      The following terms and definitions apply to this standard.

3.1

      total hydrocarbons (THC)

Refers to the sum of gaseous organic compounds that respond on the hydrogen flame ionization detector of a gas chromatograph under the measurement conditions specified in this standard.

3.2

      nonmethane hydrocarbons (NMHC)

Refers to the sum of other gaseous organic compounds after deducting methane from the total hydrocarbons under the measurement conditions specified in this standard (unless otherwise stated, the results are in carbon terms).

4 Principles of the method

The gas sample was directly injected into a gas chromatograph with a hydrogen flame ionization detector, and the contents of total hydrocarbons and methane were measured on the total hydrocarbon column and the methane column, respectively, and the difference between the two was the content of non-methane total hydrocarbons.
