附錄：藥典二氧化碳中碳氫化合物的測定

取本品作為供試品；取甲烷含量為0.0020%的氣體（以氮氣為稀釋劑）作為對照氣體，照氣相色譜法（通則0521）試驗，用玻璃球為填料的色譜柱（0.8m×4mm，80目）；柱溫為110℃；進樣口溫度為110℃；檢測器溫度為120℃。量取供試品氣體與對照氣體，注入氣相色譜儀，在凈化溫度為360℃時測得的峰面積為相應空白值；量取供試品氣體與對照氣體，注入氣相色譜儀，測定峰面積，減去相應空白值后的峰面積為校正峰面積。按外標法以校正峰面積計算，含碳氫化合物（以甲烷計）不得過0.0020%。

Special purification device for carbon dioxide analysis in Chinese Pharmacopoeia
China Pharmacopoeia special purification device for carbon dioxide analysis Details:

Product name: carbon dioxide (CO2) purification device

Model: HHO-III Purification

Application: Determination of hydrocarbons in carbon dioxide in Chinese Pharmacopoeia by gas chromatography
HHO-III Purification device type purification device is a special purification device (exclusive formula) developed by Tengzhou Haohan Chromatography Instrument Technology Service Co., Ltd. according to the "People's Republic of China Pharmacopoeia 2010 Edition" carbon dioxide pharmacopoeia standards Fast, the use temperature is only 360 ℃, making the instrument safer and energy-saving.
This purification device is exclusively developed by Haohan Chromatography, and installation drawings are provided free of charge to solve customers' worries. Realize the perfect fusion of purification devices and various types of gas chromatographs.

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%.
