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%.

The above are the indicators and tests for hydrocarbons in the Pharmacopoeia Carbon Dioxide 2020 Edition, and the testing equipment is a purification device. Haohan Chromatography (Shandong) Applied Technology Development Co., Ltd. adopts new technologies and develops new solutions to develop a special purification device suitable for carbon dioxide analysis of the 2020 edition of the Pharmacopoeia. The purification effect is good and fully meets the index control requirements of the 2020 edition of Pharmacopoeia for carbon dioxide.
