Capillary column determination of pharmacopoeia carbon dioxide
Capillary Column Determination of Pharmacopoeia Carbon Dioxide Details:

Specification: 30m*0.53mm
Model: HH-THC-30


Hydrocarbon is taken as the test gas, and a gas with a methane content of 0.0020% (with nitrogen as a diluent) is used as a control gas, and gas chromatography (General Rule 0521) is used to test the column with glass spheres as a filler ( 4mm × 0.8m, 80 mesh); column temperature is 110 ° C; inlet temperature is 110 ° C; detector is flame ionization detector, temperature is 120 ° C. The test gas and the control gas are measured and injected into the chromatograph. The peak area measured at the purification temperature of 360 ° C is the corresponding blank value; the gas for the test sample and the control gas are taken, injected into the chromatograph, and the peak area is measured and reduced. The peak area after the corresponding blank value is the corrected peak area. According to the external standard method, the hydrocarbon content (in terms of methane) should not exceed 0.0020%.

The determination of hydrocarbons in carbon dioxide in the Pharmacopoeia of the People's Republic of China uses a packed column of glass spheres of 0.8m*4mm. However, many pharmaceutical companies are equipped with capillary systems, so the packed columns are not suitable, otherwise it will take time and effort to renovate the instrument. low efficiency.
Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. has been advancing with the times to develop a capillary method for the determination of hydrocarbons in the Pharmacopoeia carbon dioxide, which cooperates with the packed column, with high efficiency and satisfactory results.
