2020版藥典二氧化碳測定玻璃球色譜柱 詳細信息：

碳氫化合物 取本品作為供試品氣體，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（4mm×0.8m，80目）；柱溫為110℃；進樣口溫度為110℃；檢測器為火焰離子化檢測器，溫度為120℃。量取供試品氣體與對照氣體，注入色譜儀，在凈化溫度為360℃時測得的峰面積為相應(yīng)空白值；量取供試品氣體與對照氣體，注入色譜儀，測定峰面積，減去相應(yīng)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%。

2020 Pharmacopoeia Carbon Dioxide Determination Glass Spherical Column
2020 edition of Pharmacopoeia Carbon Dioxide Determination Glass Spherical Column Details:

For hydrocarbons, take this product as the test gas, and take the gas with a methane content of 0.0020% (with nitrogen as the diluent) as the control gas, according to the gas chromatography (General Rule 0521) test, using glass balls as fillers in a chromatographic column ( 4mm×0.8m, 80 mesh); 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 chromatograph, and the peak area measured when the purification temperature is 360 °C is the corresponding blank value; The peak area after removing the corresponding blank value is the corrected peak area. Calculated based on the corrected peak area according to the external standard method, the hydrocarbon content (calculated as methane) should not exceed 0.0020%.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. keeps pace with the times. The glass sphere chromatographic column produced according to the 2020 standard is installed and used on the Agilent 7890B gas chromatograph, with high efficiency and good effect, and is well received by users.
