滕州市浩瀚色谱仪器技术服务有限公司，对非甲烷总烃自动连续监测系统进行示值误差、响应时间、零点漂移和量程漂移等性能测试，对非甲烷总烃便携式分析仪进行检出限、度、准确度等性能测试。性能测试满足相关要求后同时利用便携式催化氧化-氢火焰离子化检测器法（催化氧化-FID）、便携式气相色谱-氢火焰离子化检测器法（GC-FID）和实验室气相色谱-氢火焰离子化检测器法（GC-FID）对固定污染源非甲烷总烃自动连续监测系统进行现场比对测试。测试结果表明，在工况变动较大的情况下，便携式FID法与实验室GC-FID法测试结果相对误差为19.6%~35.1%，具有很好的可比性。以实验室GC-FID法为参比方法时，自动连续监测系统相对准确度为64.1%，不满足《固定污染源废气非甲烷总烃连续监测系统技术要求及检测方法》（HJ 1013—2018）的要求。以便携式FID为参比方法时，自动连续监测系统相对准确度分别为28.6%和35.3%，相对《固定污染源废气总烃、甲烷和非甲烷总烃的测定气相色谱法》（HJ 38—2017）方法一致性好，均能满足《HJ 1013—2018》的要求。提出，应推进便携式方法在自动连续监测系统验收和质控比对中的应用。

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.
