Determination of Carbon Dioxide and Hydrocarbons in Pharmacopoeia
Determination of Carbon Dioxide and Hydrocarbons in Pharmacopoeia Details:

Name: Chromatographic Column with Glass Ball as Filler

Granularity: 80 mesh

Specification: 0.8m*4mm

Model: HH-BLQ

Application: Determination of hydrocarbons in pharmacopoeia carbon dioxide

For hydrocarbons, this product is used as the test gas, and the gas with a methane content of 0.0020% (with nitrogen as the diluent) is used as the control gas. According to the gas chromatography (general rule 0521) test, a column filled with glass balls ( 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 control gas and inject them into the 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 chromatograph to determine the peak area and reduce The peak area after removing the corresponding blank value is the corrected peak area. According to the external standard method to calibrate the peak area, the hydrocarbon (calculated as methane) shall not exceed 0.0020%.
