2020 Pharmacopoeia Carbon Dioxide Determination Glass Spherical Column
2020 edition of Pharmacopoeia Carbon Dioxide Determination Glass Spherical Column 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. keeps pace with the times. The glass sphere chromatographic column produced according to the 2020 standard is installed and used on the Agilent 7890B gas chromatograph, with high efficiency and good effect, and is well received by users.
