Take this product as the test sample for hydrocarbons; Take a gas with a methane content of 0.0020% (using nitrogen as the diluent) as the control gas, and perform gas chromatography (General Rule 0521) according to the test. Use a glass ball packed chromatographic column (0.8m x 4mm, 80 mesh); The column temperature is 110 ℃; The inlet temperature is 110 ℃; The detector temperature is 120 ℃. Measure the gas of the test sample and the control gas, inject them into the gas chromatograph, and the peak area measured at a purification temperature of 360 ℃ is the corresponding blank value; Measure the gas of the test sample and the control gas, inject them into the gas chromatograph, measure the peak area, and subtract the corresponding blank value to obtain the corrected peak area. According to the external standard method for correcting peak area, the content of hydrocarbons (calculated as methane) shall not exceed 0.0020%.
The glass ball columns developed and produced by Haohan Chromatography include adapters, sealing gaskets, etc., which can be easily installed on Agilent 7820A, 7890B, 886088906890, HP4890, HP5890, with high column efficiency, symmetrical peak shapes, short analysis time, and high efficiency. Meet the detection requirements for hydrocarbons in carbon dioxide in the 2020 edition of the Pharmacopoeia.
The chromatographic columns are interconnected, and both the filling column and capillary column injection ports can be installed, making them simple, convenient, and fast to use.
