Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced a 4mm × 0.8m, 80 mesh glass ball packed chromatography column based on the Pharmacopoeia 2020 edition of carbon dioxide. The column separates hydrocarbons from carbon dioxide with high column efficiency, good separation, and symmetrical peak shapes. It can be installed and used in Shimadzu GC2030, which is simple, fast, and does not require instrument modification. Both the packed column system and the capillary system can be interconnected.

　　Applicable to: Thermo Fisher 1310 series, Agilent 7890 series, Shimadzu GC2010, Bruker, PE, Panno, Tianrui, Tianmei, Fuli

　　Hydrocarbons are determined by gas chromatography (General Rule 0521). The test gas is taken from this sample, and the reference gas is taken from a gas with a methane content of 0.0020% (using nitrogen as a diluent). Chromatographic conditions: A chromatographic column with glass spheres as fillers (4mm × 0.8m, 80 mesh); The column temperature is 110 ℃; The inlet temperature is 110 ℃; The detector is a flame ionization detector, and the temperature is 120 ℃. The test gas and the reference gas are precisely measured and injected into the gas chromatograph. The peak area measured at a purification temperature of 360 ℃ is the corresponding blank value; Accurately measure the test gas and reference gas, inject them separately into the gas chromatograph, measure the peak area, and subtract the corresponding blank value to obtain the peak area as the calibration peak area limit. Calculate the calibration peak area using the external standard method, and the content of hydrocarbons (calculated as methane) should not exceed 0.0020%.
