2015年版中國藥典二氧化碳玻璃球柱
2015年版中國藥典二氧化碳玻璃球柱 詳細信息：

名稱：藥典二氧化碳專用柱

規格：0.8m*4mm

粒度：80Mesh

型號：HH-BLQ

應用：藥典二氧化碳中碳氫化合物測定

碳氫化合物 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%。

2015 Chinese Pharmacopoeia Carbon Dioxide Glass Sphere
2015 Chinese Pharmacopoeia Carbon Dioxide Glass Ball Column Details:

Name: Pharmacopoeia special column for carbon dioxide

Specification: 0.8m*4mm

Granularity: 80Mesh

Model: HH-BLQ

Application: Determination of hydrocarbons in carbon dioxide in Pharmacopoeia



Hydrocarbons Take this product as the test sample; take the gas with a methane content of 0.0020% (with nitrogen as the diluent) as the control gas, and test according to the gas chromatography (General Rule 0521), using a glass ball as the packing column (0.8 m×4mm, 80 mesh); column temperature is 110℃; injection port temperature is 110℃; detector temperature is 120℃. Measure the test gas and control gas and inject them into the gas chromatograph. The peak area measured when the purification temperature is 360°C is the corresponding blank value; measure the test gas and control gas and inject them 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 calibrate the peak area, the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.
