Dimethyl ether detectorUsage

1、 Briefly describe

Dimethyl ether is a new type of green and environmentally friendly energy, and its performance isliquefied gasSimilarly, it is a new type of clean fuel that can potentially replace petroleum products. It contains oxygen, has a single component, a short carbon chain, good combustion performance, high thermal efficiency, and no residual liquid or black smoke during combustion. It is a high-quality and clean fuel. Experimental data shows that with a proportion not exceeding 25%liquefied gasWhen co firing, withliquefied gasThe latent generation ratio is 1:1. We must strictly control the mixing ratio, with a ratio of 1:5 or 1:6 in autumn and winter, and 1:4 or 1:3 in spring and summer.

2、 Method principle

liquefied gasanalysisincludeliquefied gascomponentanalysisandliquefied gasDimethyl ether, methanolanalysisExcluding alkynes, a gas chromatograph with a thermal conductivity detector is used to separate each component in the sample using a chromatographic column. The area normalization method or corrected area normalization method is used to quantify the percentage content of each component using an external standard method.
