岛津2020甲烷柱 详细信息：

名称：甲烷柱
规格：3m*3mm
型号：GDX-104
粒度：60-80目
应用：固定污染源废气，非甲烷总烃测定

滕州市浩瀚色谱仪器技术服务有限公司，用玻璃注射器(气袋)采集气体样品,以双柱单氢火焰离子化检测器的气相色谱仪直接进行测定.进样1.0mL样品分别进入汽化室的总烃柱和甲烷柱中,由于这两个柱子填充材料和长短差异,总烃先在FID上产生响应,然后甲烷在FID上产生响应.总烃的浓度扣除甲烷浓度和除烃空气氧的浓度值,即可得到非甲烷总烃(NMHC)的浓度,可以实现单次进样,同时完成总烃、甲烷、非甲烷总烃浓度的测定.研究1.37～22.3 mg/m3浓度甲烷标准气,得出甲烷标准曲线方程为Y =715X +829,r=0.9990,相对标准偏差为0.26％～1.8％,总烃标准曲线方程Y=695X+ 724,相对标准偏差为0.35％ ～ 1.4％,除烃空气(O2-N2,20.8％)相对标准偏差为0.75％.该法用于环境空气和固定污染源有组织排放中NMHC含量分析,操作简单,实验结果满意.

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.
