Determination of Carbon Dioxide in Ethylene Oxide by Gas Chromatography
Determination of Carbon Dioxide in Ethylene Oxide by Gas Chromatography Details:

Name: Packed Column
Specifications: 3m*3mm, 80-100 mesh
Model: PORAPAK Q
Application: Determination of carbon dioxide in industrial ethylene oxide

The index of carbon dioxide in industrial ethylene oxide: first-class product ≤ 0.001, first-class product ≤ 0.005 (both mass fractions), using thermal conductivity detector, but in reality, unless high-sensitivity TCD is used, it can be achieved, but the price of high-sensitivity TCD Expensive and limited use.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. improved the method for carbon dioxide in ethylene oxide, using a portable methane reformer gas chromatography FID detector for detection, and proved the improved method through repeatability and accuracy experiments. It is feasible. The external standard method is used for quantification. It has been installed on the Agilent 6890 gas chromatograph, and it runs normally, and is well received by users.
