大气非甲烷总烃自动监测毛细管柱
大气非甲烷总烃自动监测毛细管柱 详细信息：

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、精密度、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)方法一致性更好,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.

Capillary column for automatic monitoring of atmospheric non-methane total hydrocarbons
Capillary column for automatic monitoring of atmospheric non-methane total hydrocarbons Details:

Carry out performance tests such as indication error, response time, zero drift and span drift for the automatic continuous monitoring system of non-methane total hydrocarbons, and carry out performance tests such as detection limit, precision and accuracy of the portable non-methane total hydrocarbon analyzer. Performance test After meeting the relevant requirements, use the portable catalytic oxidation-hydrogen flame ionization detector method (catalytic oxidation-FID), portable gas chromatography-hydrogen flame ionization detector method (GC-FID) and laboratory gas chromatography-hydrogen flame ionization method The field comparison test of the automatic continuous monitoring system for non-methane total hydrocarbons of fixed pollution sources was carried out by the detector method (GC-FID). The relative error of the results is 19.6% to 35.1%, which has a good comparability. 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 requirements of the "fixed pollution source exhaust gas non-methane total". Hydrocarbon Continuous Monitoring System Technical Requirements and Detection Methods (HJ 1013-2018) requirements. 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 "fixed pollution source exhaust gas total hydrocarbons" , Determination of methane and non-methane total hydrocarbons by Gas Chromatography (HJ 38-2017), the method is more consistent and can meet the requirements of "HJ 1013-2018". It is proposed that portable methods should be promoted in the acceptance and testing of automatic continuous monitoring systems. Application in quality control comparison.
