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).
