Development of Chromatographic Column for Carbon Dioxide Glass Ball in Pharmacopoeia
Development of Pharmacopoeia Carbon Dioxide Glass Sphere Chromatography Column Details:

Name: Pharmacopoeia carbon dioxide (CO2) purification device

Model: HHO-III Purification device

Application: 2010 and 2015 editions, 2020 edition Chinese Pharmacopoeia Determination of hydrocarbons in carbon dioxide gas chromatography



Hydrocarbons are determined according to gas chromatography (General Principle 0521). Take this product as the test sample gas, that is, the reference sample gas should be a gas with a methane content of 0.0020% (with nitrogen as a diluent). Chromatographic conditions use a chromatographic column filled with glass balls (4mm×0.8m, 80 mesh); the column temperature is 110℃; the temperature of the injection port is 110℃; the detector is a flame ionization detector, and the temperature is 120℃. The method is precise. Measure the test gas and reference gas and inject them into the gas chromatograph respectively. The peak area measured when the purification temperature is 360°C is the corresponding blank value; accurately measure the test gas and reference gas and inject them into the gas chromatograph. The peak area is determined by the instrument, and the peak area after subtracting the corresponding blank value is the calibrated peak area limit. The peak area is calculated by the external standard method, and the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times and develops a 1m*1/8 inch glass bulb column suitable for Agilent 7890B gas chromatograph according to the specifications of the instrument. The installation is simple and fast, and the results are accurate and reliable. .
