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。

nitoring 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, respo
nse time, zero drift and range drift of non-methane total hydrocarbon automatic co
ntinuous mo
nitoring 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 io
nization detector method (catalytic oxidation-FID), portable gas chromatography-hydrogen flame io
nization detector (GC-FID) and laboratory gas chromatography-hydrogen flame The io
nization detector method (GC-FID) performs on-site comparison test on the automatic co
ntinuous mo
nitoring 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 co
ndition 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 co
ntinuous mo
nitoring system is 64.1%, which does not meet the technical requirements and detection methods of the co
ntinuous pollution source non-methane total hydrocarbon co
ntinuous mo
nitoring system (HJ 1013-2018). Claim. When the portable FID is used as the reference method, the relative accuracy of the automatic co
ntinuous mo
nitoring 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 co
nsistent and can meet the requirements of HJ 1013-2018. It is proposed that the application of portable methods in the acceptance and quality co
ntrol comparison of automatic co
ntinuous mo
nitoring systems should be promoted.
