大气中甲烷、总烃及非甲烷总烃监测
大气中甲烷、总烃及非甲烷总烃监测 详细信息：

甲烷柱：GDX-502，2m*3mm，2m*4mm，2m*1/8
总烃柱：2m*4mm，2m*3mm，2m*1/8，硅烷化玻璃微球

滕州市浩瀚色谱仪器技术服务有限公司，采用六通阀进样,双填充柱、双FID检测器气相色谱法,一次进样即可测得大气中的CH4、总烃及非甲烷总烃(NMHC)的测试数据.同时对色谱中FID检测器中出现的氧峰初步可认定为"干扰峰",在分析中可忽略不计.方法的检出限:CH40.03 mg/m3,总烃0.04 mg/m3,NMHC 0.06 mg/m3.变异系数:CH43.81%,总烃2.07%,NHMC 5.07%.加标回收率:CH496.1%,NHMC 96.1%～98%.

Monitoring of methane, total hydrocarbons and non-methane total hydrocarbons in the atmosphere
Monitoring of methane, total hydrocarbons and non-methane total hydrocarbons in the atmosphere Details:

Methane column: GDX-502, 2m*3mm, 2m*4mm, 2m*1/8
Total hydrocarbon column: 2m*4mm, 2m*3mm, 2m*1/8, silanized glass microspheres

Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. uses six-port valve injection, double packed column and double FID detector gas chromatography to measure CH4, total hydrocarbons and non-methane total hydrocarbons in the atmosphere (NMHC). Test data. At the same time, the oxygen peak appearing in the FID detector in the chromatogram can be initially identified as "interference peak", which is negligible in the analysis. The detection limit of the method: CH40.03 mg/m3, total hydrocarbon 0.04 mg / m3, NMHC 0.06 mg / m3. Coefficient of variation: CH 43.81%, total hydrocarbons 2.07%, NHMC 5.07%. Standard addition recovery: CH496.1%, NHMC 96.1% ~ 98%.
