Chinese Pharmacopoeia 2020 Carbon Dioxide Glass Sphere
Chinese Pharmacopoeia 2020 Carbon Dioxide Glass Sphere Details:

Name: Pharmacopoeia special column for carbon dioxide

Specification: 4mm×0.8m, 80 mesh

Granularity: 80 mesh

Model: HH-BLQ

Application: Determination of Hydrocarbons in Carbon Dioxide in Pharmacopoeia Chinese Pharmacopoeia 2020 Edition

Hydrocarbons are determined according to gas chromatography (General Principle 0521) to take this product, and the reference gas is obtained. The gas with methane content of 0.0020% (with nitrogen as the diluent). The chromatographic conditions use a chromatographic column filled with glass balls (4mm×0.8m, 80 mesh); the column temperature is 110°C; the inlet temperature is 110°C; the detector is a flame ionization detector, and the temperature is 120°C. The measurement 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 as the calibrated peak area by the external standard method, and the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.
