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 reference gas, and perform the gas chromatography test according to General Rule 0521. Use a chromatographic column (0.8m) filled with glass balls × 4mm, 80 mesh); The column temperature is 110 ℃; The inlet temperature is 110 ℃; The detector temperature is 120 ℃. Measure the test sample gas and control gas, inject them into a gas chromatograph, and the peak area measured at a purification temperature of 360 ℃ is the corresponding blank value; Measure the test sample gas and control gas, inject them into a gas chromatograph, measure the peak area, and subtract the corresponding blank value to obtain the corrected peak area. Calculated using the external standard method to correct peak area, the hydrocarbon content (calculated as methane) shall not exceed 0.0020%.
The above is the requirement for carbon dioxide in the pharmacopoeia, and the core component analyzed is the purification device. Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. is keeping up with the times and according to the requirements of the Pharmacopoeia, has developed the HHO-III Purification device for carbon dioxide purification. The purification effect is good, and it has been installed and tested in pharmaceutical units with high efficiency, simple installation, no need to modify the instrument, and short analysis time. This product is a characteristic product of Haohan Chromatography. Welcome to consult and negotiate.
