?
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(biāo)法以校正峰面積計算，含碳氫化合物（以甲烷計）不得過0.0020%。

Name: Chromatographic Column
Fixed phase: glass ball
Granularity: 80mesh
Specification: 0.8m * 4mm
Model: HH-BLQ
Application: Analysis of Hydrocarbons in Carbon Dioxide in the 2015/2020 Pharmacopoeia
The glass sphere chromatography column developed by Haohan Chromatography has high column efficiency and good separation. It can be interconnected with instruments such as Shimadzu, Thermo Fisher Scientific, Varian, Brooke, PE, Panno, Fuli, and Beifen Raleigh, and the results are satisfactory.
Reference method:
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).
