*High operating temperature: 300°C
Application: Determination of HJ2017 ambient air, stationary pollution source waste gas, total hydrocarbons, methane, and non-methane total hydrocarbons by gas chromatography

As an important indicator of volatile organic compound pollution, the monitoring data of non-methane total hydrocarbons can directly reflect the degree of VOCs pollution, which is of great significance to environmental governance and management. Air bag method sampling, ten-port valve injection, double-column single-FID gas chromatography to determine the concentration of non-methane total hydrocarbons in waste gas, through the evaluation of the uncertainty of the entire monitoring process, find out the factors that have the greatest impact on the accuracy of the monitoring results In order to fit the calibration curve, an improved method to improve the accuracy of the monitoring results is proposed.
