| titleOfInvention | Column chromatography liquid adding device for separating tobacco leaf and tea leaf extracts |
| abstract | The utility model provides a column chromatography liquid feeding device for separation of tobacco leaf and tealeaves extract product mainly includes: the device comprises a liquid storage device, an inverted double-layer funnel and a chromatographic column which are sequentially connected from bottom to top. The inverted double-layer funnel comprises a regulating valve and a funnel main body, wherein an air outlet is formed in the upper part of the outer layer of the funnel main body, and the top end of the inner layer is a hemispherical smooth surface. When the mobile phase is added into the chromatographic column through the liquid storage device, the mobile phase can uniformly flow to the stationary phase along the inner wall of the chromatographic column. Compared with the prior art, the utility model can reduce the manual operation times when separating and purifying the extracts of the tobacco leaves and the tea leaves, and avoid the pollution of the sample caused by adding the mobile phase into the chromatographic column by repeatedly using the rubber dropper manually; the mobile phase flows into the stationary phase along the inner wall of the chromatographic column uniformly, so that the flat surface of the stationary phase is kept, and the separation and purification effects are improved. |
