National Standard HJ/T 38-2017 Fixed Pollution Source Exhaust Gas Determination of Non-Methane Total Hydrocarbons Gas Chromatography


Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. carried out comparative monitoring of the non-methane total hydrocarbon online monitoring system of fixed pollution sources of typical enterprises, and analyzed the correlation between automatic monitoring system and manual method monitoring data; passed performance index testing and method comparison Obtain basic data such as system performance indicators and test results. The test results show that different sampling and analysis instruments are used in the actual sample comparison process, and the monitoring results have a large gap, with a relative error of 1.23% to 108.1%. The portable analyzer results have relatively small relative errors, and the laboratory analysis results have relatively large relative errors. The linear error and range drift of the system can meet the management requirements at this stage, and suggestions for the operation and management of the online monitoring system are put forward based on the test results.
