島津Porapak Q甲烷柱 詳細(xì)信息：

名稱：甲烷柱
規(guī)格：0.8m，1.5m*1/8
型號：Porapak Q
應(yīng)用：氣相色譜法測定總烴與非甲烷總烴

滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，采用十通閥、雙定量環(huán)進(jìn)樣(進(jìn)樣量0.5 mL),專用的甲烷柱和總烴柱分別分離兩路氣樣,單FID檢測器檢測的方法測定環(huán)境空氣和固定污染源廢氣中的總烴和非甲烷總烴(NMHC).實(shí)驗(yàn)結(jié)果表明:總烴與甲烷工作曲線的相關(guān)系數(shù)分別為0.997 7和0.999 0;總烴與甲烷測定結(jié)果的相對標(biāo)準(zhǔn)偏差均未超過1.5％;總烴與NMHC的檢出限均為0.04 mg/m3;總烴的加標(biāo)回收率為90.3％～113.0％,NMHC的加標(biāo)回收率為91.1％～110.0％.上述指標(biāo)均滿足HJ 604-2011和HJ/T 38-1999中對總烴及NMHC的測定要求.用注射器采樣后的氣樣應(yīng)盡量避光保存,放置時(shí)間宜在8h之內(nèi).該方法無需制備除烴空氣,大幅提升了檢測效率.

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.
