Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. uses glass ball packed column gas chromatography to determine the content of hydrocarbons in pharmacopoeia carbon dioxide, which is a mature and highly specific method. The core lies in the use of inert glass ball packing chromatography columns for separation, FID detector detection, and quantification through external standard method to ultimately determine whether the hydrocarbon impurities in the product are below the limit of 0.0020%.
Required materials and equipment
Gas chromatograph system: A hydrogen flame ionization detector (FID) and corresponding gas injection valve or manual injection system 1 are required.
Glass sphere chromatography column: This is the core component. Recommend using a chromatography column with a length of 0.8m and an inner diameter of 4mm, filled with 80 mesh glass spheres (HH-BLQ model of Haohan Chromatography). This type of column is inert and has good separation ability for low-carbon hydrocarbons (such as methane) in the carbon dioxide matrix.
High purity carrier gas and detector gas: High purity nitrogen or helium gas is usually used as the carrier gas. Hydrogen and air (or compressed air) are used as combustion gases and auxiliary gases for FID. It is necessary to ensure the purity of the gas, and the oxygen content in the carrier gas should preferably not exceed 1 ppm to avoid damaging the chromatographic column stationary phase or affecting the baseline at high temperatures.
Standard gas: Methane standard gas, with a concentration of 0.0020% (volume fraction) of methane in nitrogen, used for external standard method quantification of 36.
Carbon dioxide sample to be tested: the carbon dioxide sample specified in the pharmacopoeia
Name: Glass Ball Chromatography Column
Specification: 0.8m * 4mm, 80 mesh
Maximum operating temperature: 300 ° C
Application: Pharmacopoeia Carbon Dioxide 2020 Edition: Determination of Hydrocarbons
Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. has developed and produced glass sphere chromatography columns that are installed on instruments such as Shimadzu, Agilent, Thermo Fisher Scientific, Varian, Bruker, PE, etc. The columns have high column efficiency, good separation, symmetrical peak shapes, and meet the requirements of pharmacopoeia.
