Propane/toluene/ethyl acetate/trichloroethylene/standard gas Details:

In order to standardize the installation and acceptance, daily operation and maintenance and quality control of ambient air non-methane total hydrocarbons continuous monitoring system, and to improve the quality of ambient air non-methane total hydrocarbons automatic monitoring data, the China Environmental Monitoring Station and Shanghai Environmental Monitoring Center and other units are formed. The compilation team has studied and formulated the "Technical Regulations for Continuous Automatic Monitoring System for Non-methane Total Hydrocarbons in Ambient Air (Trial Implementation)" (hereinafter referred to as "Technical Regulations"), and issued the National Ecological Environment Monitoring System for trial implementation in January 2021.

1000 ppbC standard gas such as propane, toluene, ethyl acetate, trichloroethylene,
50 ppbC propane standard gas

The highest point of the non-methane total hydrocarbon calibration curve is recommended to be 1000 ppbC, and the lowest point of the calibration curve is recommended to be 1000 ppbC.
50 ppbC is recommended; 5000 ppb is recommended for the highest point of the methane calibration curve and 5000 ppb for the lowest point of the calibration curve
1000 ppb is recommended.

1000 ppbC undecane standard gas
