Automatic continuous monitoring of non-methane total hydrocarbons from stationary sources
Automatic continuous monitoring of non-methane total hydrocarbons from stationary sources.

Stationary phase: modified molecular sieve
Specification: 30m*0.53mm*25um
Model: HH-PLOT-Molecular sieve
Application: Technical Requirements and Test Methods for Continuous Monitoring System for Non-Methane Total Hydrocarbons from Fixed Sources of Waste Gas (HJ 1013-2018)
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. performs performance tests on indication error, response time, zero drift and range drift of non-methane total hydrocarbon automatic continuous monitoring system, and detects and limits the non-methane total hydrocarbon portable analyzer. Performance testing such as degree and accuracy. The performance test meets the relevant requirements while using the portable catalytic oxidation-hydrogen flame ionization detector method (catalytic oxidation-FID), portable gas chromatography-hydrogen flame ionization detector (GC-FID) and laboratory gas chromatography-hydrogen flame The ionization detector method (GC-FID) performs on-site comparison test on the automatic continuous monitoring system of non-methane total hydrocarbons with fixed pollution sources. The test results show that the relative error between the portable FID method and the laboratory GC-FID method is 19.6%~35.1% under the condition of large changes in working conditions, which is very comparable. When the laboratory GC-FID method is used as the reference method, the relative accuracy of the automatic continuous monitoring system is 64.1%, which does not meet the technical requirements and detection methods of the continuous pollution source non-methane total hydrocarbon continuous monitoring system (HJ 1013-2018). Claim. When the portable FID is used as the reference method, the relative accuracy of the automatic continuous monitoring system is 28.6% and 35.3%, respectively, compared with the "Gas Chromatography for Determination of Total Hydrocarbons, Methane and Non-Methane Total Hydrocarbons from Fixed Sources" (HJ 38-2017) The method is more consistent and can meet the requirements of HJ 1013-2018. It is proposed that the application of portable methods in the acceptance and quality control comparison of automatic continuous monitoring systems should be promoted.
