Agilent 7890B Application 2020 Pharmacopoeia Carbon Dioxide Glass Sphere Column 4mm*0.8m Details:

 For hydrocarbons, take this product as the test gas, and take the gas with a methane content of 0.0020% (with nitrogen as the diluent) as the control gas, according to the gas chromatography (General Rule 0521) test, using glass balls as fillers in a chromatographic column ( 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 the reference gas, inject them into the chromatograph, and the peak area measured when the purification temperature is 360 °C is the corresponding blank value; The peak area after removing the corresponding blank value is the corrected peak area. Calculated based on the corrected peak area according to the external standard method, the hydrocarbon content (calculated as methane) should not exceed 0.0020%.

Haohan Chromatography (Shandong) Application Technology Development Co., Ltd., according to the requirements in the 2020 edition of the Pharmacopoeia carbon dioxide, produced a glass sphere chromatographic column that was installed and tested on an Agilent 7890B gas chromatograph, with satisfactory results and high praise from users.
