島津2020甲烷柱 詳細(xì)信息：

名稱：甲烷柱
規(guī)格：3m*3mm
型號：GDX-104
粒度：60-80目
應(yīng)用：固定污染源廢氣，非甲烷總烴測定

滕州市浩瀚色譜儀器技術(shù)服務(wù)有限公司，用玻璃注射器(氣袋)采集氣體樣品,以雙柱單氫火焰離子化檢測器的氣相色譜儀直接進(jìn)行測定.進(jìn)樣1.0mL樣品分別進(jìn)入汽化室的總烴柱和甲烷柱中,由于這兩個(gè)柱子填充材料和長短差異,總烴先在FID上產(chǎn)生響應(yīng),然后甲烷在FID上產(chǎn)生響應(yīng).總烴的濃度扣除甲烷濃度和除烴空氣氧的濃度值,即可得到非甲烷總烴(NMHC)的濃度,可以實(shí)現(xiàn)單次進(jìn)樣,同時(shí)完成總烴、甲烷、非甲烷總烴濃度的測定.研究1.37～22.3 mg/m3濃度甲烷標(biāo)準(zhǔn)氣,得出甲烷標(biāo)準(zhǔn)曲線方程為Y =715X +829,r=0.9990,相對標(biāo)準(zhǔn)偏差為0.26％～1.8％,總烴標(biāo)準(zhǔn)曲線方程Y=695X+ 724,相對標(biāo)準(zhǔn)偏差為0.35％ ～ 1.4％,除烴空氣(O2-N2,20.8％)相對標(biāo)準(zhǔn)偏差為0.75％.該法用于環(huán)境空氣和固定污染源有組織排放中NMHC含量分析,操作簡單,實(shí)驗(yàn)結(jié)果滿意.

Shimadzu 2020 methane column
Shimadzu 2020 methane column Details:

Name: Methane Column
Specification: 3m*3mm
Model: GDX-104
Granularity: 60-80 mesh
Application: Determination of waste gas from stationary sources, non-methane total hydrocarbons

Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. used a glass syringe (air bag) to collect gas samples, and directly measured them with a gas chromatograph with a dual-column single-hydrogen flame ionization detector. The 1.0mL sample was injected into the total volume of the vaporization chamber. In the hydrocarbon column and the methane column, due to the difference in the packing materials and length of the two columns, total hydrocarbons first respond on the FID, and then methane responds on the FID. The concentration of total hydrocarbons deducts the concentration of methane and the concentration of air oxygen in addition to hydrocarbons. , The concentration of non-methane total hydrocarbons (NMHC) can be obtained, and a single injection can be realized, and the concentration of total hydrocarbons, methane, and total non-methane hydrocarbons can be determined at the same time. Study the methane standard gas with a concentration of 1.37～22.3 mg/m3 to obtain The methane standard curve equation is Y = 715X +829, r=0.9990, the relative standard deviation is 0.26% ~ 1.8%, and the total hydrocarbon standard curve equation is Y = 695X + 724, the relative standard deviation is 0.35% ~ 1.4%, except for hydrocarbon air (O2 -N2, 20.8%) The relative standard deviation is 0.75%. This method is used for the analysis of NMHC content in ambient air and organized emissions from fixed pollution sources. The operation is simple and the experimental results are satisfactory.
