A sample mixing device applied to column chromatography

Abstract

The invention discloses a sample stirring device applied to column chromatography. The sample stirring device applied to the column chromatography comprises a separating funnel, an adsorption cup body, a revolving cup, a condenser and an air conveying device. The adsorption cup body is of a cylindrical basis pyramidis structure, a filter plate is arranged at the bottom of the adsorption cup body, and a movable filter plate is arranged in the adsorption cup body; an adsorption cup is provided with a cup cover and a sealing gasket used for sealing, and a small hole is formed in the middle of the cup cover, so that the cup cover can be detachably connected with the separating funnel and an air pipe in a sealed mode; a micropipe is connected with the bottom of the adsorption cup body, and a valve is arranged on the micropipe, so that the bottom of the adsorption cup body can be detachably connected with the revolving cup and the condenser in a sealed mode; the condenser is of a jacketed structure and made from red copper or aluminum, the condenser is provided with red copper or aluminum fin, and the condenser is filled with red copper or aluminum metallic packing. The sample stirring device applied to the column chromatography has the advantages that the scheme is simple and reliable and easy to achieve, and the condensing efficiency is very high; the desolvation of the fluidized chromatographic packing is thorough and efficient, and lower content of air discharging solvent is achieved through secondary condensing of water bath solvent steam; the adsorption and drying of resins to the sample are completely achieved, efficiency, simpleness and complete recycling of the solvent are simultaneously achieved, and stronger practicality is achieved.

Description

technical field [0001] The invention relates to a sample mixing device applied to column chromatography. Background technique [0002] Sample mixing is to dissolve the sample with a solvent and then adsorb it with a chromatographic packing, and finally carry out desolvation and drying. The chromatographic packing includes silica gel, dextran, resin, etc., but no matter what kind of packing it is, it is hoped that the adsorption will be saturated as much as possible, so as to have High column efficiency. However, in actual operation, it is often difficult for the filler to be adsorbed to saturation, and the subsequent desolventization is generally done by draining and drying naturally or by a rotary evaporator. The operation process cannot be continuous, and the operation is troublesome, and the loss of solvent is also high. very big. [0003] Therefore, if a continuous and convenient sample mixing device is designed, which can saturate the adsorption of the chromatographic...
