The technical indicators specified in the pharmacopoeia need to be strictly controlled by the manufacturing enterprise. The core component of pharmacopoeia carbon dioxide analysis is the purification device.

　　Pharmacopoeia description:

　　Measure the gas of the test sample and the control gas, inject them into the chromatograph, and the peak area measured at a purification temperature of 360 ℃ is the corresponding blank value; Measure the gas of the test sample and the control gas, inject them into the chromatograph, measure the peak area, and subtract the corresponding blank value to obtain the corrected peak area. According to the external standard method for correcting peak area, the content of hydrocarbons (calculated as methane) shall not exceed 0.0020%.
