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%.
