| titleOfInvention | A device for accelerating the preparation of petroleum samples |
| abstract | The utility model discloses a device for accelerating the preparation of petroleum samples, which relates to the technical field of sample preparation. The utility model comprises a chromatography column, a piston, a leather tube, a syringe and a top cover. A filter element is arranged in the lower part of the chromatography column. A first glass wool layer is arranged on the upper surface of the filter element in the chromatography column. The surface is provided with a magnesium silicate adsorption column, the upper surface of the magnesium silicate adsorption column is provided with a second glass wool layer, the upper surface of the second glass wool layer is provided with an anhydrous sodium sulfate layer, and the piston is fixed on the axis of the bottom surface of the top cover through a fixing rod At the top, the top cap thread is set at the top of the chromatography column. The utility model sucks the extraction liquid through a syringe and discharges it into the chromatographic column, and pushes the extraction liquid through the air pressure, which can provide pressure and improve the passing efficiency of the extraction liquid, thereby improving the elution and adsorption efficiency and effect of the chromatographic column, and It has the effect of removing water and improves the preparation effect and efficiency of petroleum samples. |
