Appendix: Determination of hydrocarbons in carbon dioxide of Pharmacopoeia

Take this product as a test product; take a gas with methane content of 0.0020% (using nitrogen as a diluent) as a control gas, and test it according to gas chromatography (General Rule 0521), using a glass ball as a packing column (0.8m × 4mm) , 80 mesh); column temperature is 110 ℃; inlet temperature is 110 ℃; detector temperature is 120 ℃. Measure the test gas and the control gas and inject it into the gas chromatograph. The peak area measured at the purification temperature of 360 ℃ is the corresponding blank value; measure the test gas and the control gas and inject it into the gas chromatograph to determine the peak area The peak area after subtracting the corresponding blank value is the corrected peak area. According to the external standard method to calculate the corrected peak area, hydrocarbons (calculated as methane) should not exceed 0.0020%.
