Hydrocarbons are measured by gas chromatography (General Rule 0521) and the gas of the test product is taken from this product, that is, the reference gas is obtained as a gas with a methane content of 0.0020% (with nitrogen as the diluent). Chromatographic conditions: Use a chromatographic column (4mm×0.8m, 80 mesh) with glass balls as filler; 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. Measure the test gas and the reference gas, inject them into the gas chromatograph respectively, and the peak area measured when the purification temperature is 360 ℃ is the corresponding blank value; accurately measure the test gas and the reference gas, and inject them into the gas chromatograph respectively. Instrument, measure the peak area, and the peak area after subtracting the corresponding blank value is the calibration peak area limit. Calculate the calibration peak area according to the external standard method, and the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.
The above are the standards for hydrocarbons in carbon dioxide in the 2020 edition of the Chinese Pharmacopoeia:
