Determination of Pharmacopoeia Carbon Dioxide by HH-THC-30-II Inlet Tube Capillary Column
HH-THC-30-II inlet tube capillary column for determination of Pharmacopoeia CO2 Details:
According to the customer's reaction, the domestic tube body is not flexible enough, brittle and easy to break. Tengzhou Haohao Chromatography Instrument Technology Service Co., Ltd. adopts imported tube body, which has good elasticity, softness and long service life.
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. The gas chromatographic method (General Rule 0521) is used to test the column with a glass sphere 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%.
