Abstract

The invention discloses a single-column chromatographic column for electric insulation oil gas separation. The single-column chromatographic column comprises a column tube body and a filling material, wherein the column tube body is filled with the filling material; the two ends of the column tube body are sealed with filter screens. The single-column chromatographic column is characterized in that the filling material is prepared by mixing Hayesep D stationary phase and Hayesep N stationary phase of 80 to 100 meshes. The single-column chromatographic column has the benefits of high detection precision, simplified variety of the filling material, high degree of separation and good column efficiency. The invention further discloses a preparation method for the single-column chromatographic column for separating electric insulation oil gas.

Description

technical field [0001] The invention relates to a single-column chromatographic column for separating oil and gas used for electric insulation, and a preparation method of the single-column chromatographic column. Background technique [0002] Gas chromatography is a new separation and analysis technique developed rapidly after the 1970s. The essence of the separation of the mixture in the chromatographic column is that the mixture has different distribution coefficients between the two phases. When the components in the mixture enter the chromatographic column, those components with small distribution coefficients are distributed repeatedly in the two phases. , resulting in considerable separation efficiency, and finally the different components are completely separated, and the separated components are detected on the detector. Only when the separation is complete can each component be accurately identified, so the chromatographic column can be called the liver of the chr...
