Shimadzu 岛津Porapak Q甲烷柱的详细资料

岛津Porapak Q甲烷柱
岛津Porapak Q甲烷柱 详细信息：

名称：甲烷柱
规格：0.8m，1.5m*1/8
型号：Porapak Q
应用：气相色谱法测定总烃与非甲烷总烃

滕州市浩瀚色谱仪器技术服务有限公司，采用十通阀、双定量环进样(进样量0.5 mL),专用的甲烷柱和总烃柱分别分离两路气样,单FID检测器检测的方法测定环境空气和固定污染源废气中的总烃和非甲烷总烃(NMHC).实验结果表明:总烃与甲烷工作曲线的相关系数分别为0.997 7和0.999 0;总烃与甲烷测定结果的相对标准偏差均未超过1.5％;总烃与NMHC的检出限均为0.04 mg/m3;总烃的加标回收率为90.3％～113.0％,NMHC的加标回收率为91.1％～110.0％.上述指标均满足HJ 604-2011和HJ/T 38-1999中对总烃及NMHC的测定要求.用注射器采样后的气样应尽量避光保存,放置时间宜在8h之内.该方法无需制备除烃空气,大幅提升了检测效率.

Shimadzu Porapak Q methane column
Shimadzu Porapak Q methane column Details:

Name: Methane Column
Specification: 0.8m, 1.5m*1/8
Model: Porapak Q
Application: Determination of total hydrocarbons and non-methane total hydrocarbons by gas chromatography

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd., adopts ten-port valve, double loop injection (injection volume 0.5 mL), dedicated methane column and total hydrocarbon column to separate two gas samples, single FID detector detection method Determination of total hydrocarbons and non-methane total hydrocarbons (NMHC) in ambient air and stationary pollution source exhaust gas. Experimental results show that the correlation coefficients of the working curves of total hydrocarbons and methane are 0.997 7 and 0.999 0, respectively; the relative standard of total hydrocarbon and methane determination results The deviation does not exceed 1.5%; the detection limits of total hydrocarbons and NMHC are both 0.04 mg/m3; the standard addition recovery rate of total hydrocarbons is 90.3%-113.0%, and the standard addition recovery rate of NMHC is 91.1%-110.0%. The indicators meet the requirements for the determination of total hydrocarbons and NMHC in HJ 604-2011 and HJ/T 38-1999. The gas sample after sampling with a syringe should be stored in the dark as much as possible, and the storage time should be within 8 hours. This method does not require preparation and removal. Hydrocarbon air greatly improves the detection efficiency.
