本品含CO2不得少于99.5%（ml/ml）。
【性状】 本品为无色气体；无臭；水溶液显弱酸性反应。
本品1容在常压20℃时，能溶于水约1容中。
【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。
（2）本品能使火焰熄灭。
（3）本品的红外光吸收图谱应与对照的图谱（图1）一致（通则0402）。

碳氢化合物 取本品作为供试品气体，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）试验，用玻璃球为填料的色谱柱（4mm×0.8m，80目）；柱温为110℃；进样口温度为110℃；检测器为火焰离子化检测器，温度为120℃。量取供试品气体与对照气体，注入色谱仪，在净化温度为360℃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%。

浩瀚色谱（山东）应用技术开发有限公司，依据药典二氧化碳研制的玻璃球柱，柱效高，分离好，0.5min即可完成一次进样，在安捷伦6890,7890,7820A，8860,8890上均可实现毛细管柱/填充柱的互联互通，用户满意。

This product must contain no less than 99.5% CO2 (ml/ml).
【 Appearance 】 This product is a colorless gas; Odorless; The aqueous solution exhibits weak acidic reaction.
This product can dissolve in about 1 volume of water at 20 ℃ atmospheric pressure.
[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.
(2) This product can extinguish flames.
(3) The infrared absorption spectrum of this product should be consistent with the reference spectrum (Figure 1) (General Rule 0402).
Hydrocarbons: This product is used as the test gas, and a gas with a methane content of 0.0020% (diluted with nitrogen) is used as the control gas. The gas chromatography method (General Rule 0521) is used for testing, and a chromatography column (4mm × 0.8m, 80 mesh) filled with glass spheres is used; The column temperature is 110 ℃; The inlet temperature is 110 ℃; The detector is a flame ionization detector with a temperature of 120 ℃. Measure the test gas and control gas, inject them into the chromatograph, and measure the peak area at a purification temperature of 360 ℃ as the corresponding blank value; Measure the test gas and 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, the corrected peak area should not exceed 0.0020% for hydrocarbons (calculated as methane).
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed a glass column based on pharmacopoeia carbon dioxide. The column has high efficiency and good separation, and can complete one injection in 0.5 minutes. The interconnection between capillary column and packed column can be achieved on Agilent 689078907820A and 88608890, and the user is satisfied.
Specification: 0.8m * 4mm, 80 mesh
