Carbon Dioxide
CO2 44.01
[124-38-9]
本品含CO2不得少于99.5%（ml/ml）。
【性状】本品为无色气体。
【鉴别】（1）取本品，通入氢氧化钡试液中，即生成白色沉淀；沉淀能在醋酸中溶解并发生泡沸。
碳氢化合物 取本品作为供试品；取甲烷含量为0.0020%的气体（以氮气为稀释剂）作为对照气体，照气相色谱法（通则0521）测定，用玻璃球为填料的色谱柱（0.8m×4mm, 80目）；柱温为110℃；检测器温度为250℃。量取供试品气体与对照气体，注入气相色谱仪，在净化温度为360℃（脱烃）时测得的峰面积为相应空白值；量取供试品气体与对照气体，注入气相色谱仪，测定峰面积，减去相应空白值后的峰面积为校正峰面积。按外标法以校正峰面积计算，含碳氢化合物（以甲烷计）不得过0.0020%。

This product must contain no less than 99.5% CO2 (ml/ml).
【 Appearance 】 This product is a colorless gas.
[Identification] (1) Take this product and pour it into the barium hydroxide test solution to generate a white precipitate; Sediments can dissolve in acetic acid and undergo boiling.
Take this product as the test sample for hydrocarbons; Take a gas with a methane content of 0.0020% (using nitrogen as a diluent) as the control gas, and measure it according to the gas chromatography method (General Rule 0521) using a chromatography column packed with glass spheres (0.8m × 4mm, 80 mesh); The column temperature is 110 ℃; The detector temperature is 250 ℃. Measure the test gas and control gas, inject them into the gas chromatograph, and measure the peak area at a purification temperature of 360 ℃ (dehydrogenation) as the corresponding blank value; Measure the test gas and control gas, inject them into the gas chromatograph, measure the peak area, and subtract the corresponding blank value to obtain the corrected peak area. According to the external standard method, the corrected peak area should not exceed 0.0020% for hydrocarbons (calculated as methane).
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced the HHO-III Purification device purification device based on the requirements of the Pharmacopoeia Carbon Dioxide 2025 edition for hydrocarbons. The installation is simple and fast. The quantitative determination of hydrocarbons using the area external standard method yielded satisfactory results.
