Pharmacopoeia Carbon Dioxide Index Requirements:
Hydrocarbons are measured using gas chromatography (General Rule 0521) to obtain the reference gas, which is a gas with a methane content of 0.0020% (using nitrogen as the diluent). Chromatographic conditions: Chromatographic column filled with glass balls (4mm × 0.8m, 80 mesh); The column temperature is 110 ℃; The inlet temperature is 110 ℃; The detector is a flame ionization detector, with a temperature of 120 ℃. The test gas and reference gas are accurately measured and injected into a gas chromatograph. The peak area measured at a purification temperature of 360 ℃ is the corresponding blank value; Accurately measure the test sample gas and the control sample gas, inject them into a gas chromatograph, measure the peak area, subtract the corresponding blank value, and the peak area is the corrected peak area limit. Calculate the corrected peak area using the external standard method, and the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.
