名稱：填充柱
規格：3m*3mm，80-100目
型號:PORAPAK Q
應用：工業環氧乙烷中二氧化碳的測定

工業環氧乙烷中二氧化碳的指標：優等品≤0.001，一等品≤0.005（均為質量分數），采用熱導檢測器，然而現實中除非采用高靈敏度TCD方可實現，但高靈敏度TCD價格高昂，使用受限。

浩瀚色譜（山東）應用技術開發有限公司對環氧乙烷中二氧化碳的方法進行改進,采用便攜式甲烷轉化爐氣相色譜法FID檢測器進行檢測,通過進行重復性試驗和準確性實驗證明改進后的方法切實可行.，外標法定量，在安捷倫6890氣相色譜儀上安裝完畢，運行正常，受到用戶的好評。

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.
