Embodiment 1

[0015] This embodiment provides a sample loader for Sephadex low-pressure chromatography on a glass column with an inner diameter of 25 mm.

[0016] See attached figure 1 , a column chromatography sample loading device provided in this embodiment, which includes a sample loader 1 and a socket 5, the sample chamber adopts a medical common syringe; one end of the sample loader 1 is a tapered mouth 3, and the middle is a cavity 2 , There is a sampling hole 4 around the cavity 2; one end of the sleeve 5 is connected to the tapered mouth 3 of the sample loading device 1, and the other end is connected to the injection outlet of the ordinary syringe.

[0017] There can be 12 to 16 sampling holes with a diameter of 0.1 to 1.0 mm.

[0018] The outer diameter of the cylinder of the sample loader can be 0.5-5 mm smaller than the inner diameter of the column chromatography tube.

[0019] The sample loader is made of polytetrafluoroethylene resin resistant to organic solvents and strong...

Abstract

The invention discloses a sample loading device for common or low-pressure column chromatography, which comprises a sample loader (1), a socketed pipe (5) and a sample cavity; the sample loader (1) is of a cylinder flat shape; one end of the sample loading device is provided with a bell (3), the middle thereof is provided with a cavity (2) and the perimeter thereof is provided with sample discharging holes (4); when a common injector is adopted, the sample cavity is directly connected with the sample loader after a certain amount of filter sample liquid is extracted, or is connected with the sample loader through the socketed pipe (5) and is integrally placed above a column chromatography packed bed, so that the sample liquid rapidly enters from a compressor into the sample loader throughthe socketed pipe and is sprayed out in a mode of liquid frost or flows out in a mode of water-drop from the holes around, and rapidly and evenly flows into a chromatographic column from the pipe wall of the column chromatography packed bed to finish the sample loading operation. The device of the invention has low manufacturing cost, rapid sample loading speed, evenly sample spreading and convenient operation, and can be widely applied to the chromatographic analysis for a laboratory, industry production and the like.

Description

technical field [0001] The invention relates to a sample loading device for common column chromatography or low pressure column chromatography. Background technique [0002] With the increasingly wide application of liquid chromatography separation technology, the sample loading technology of high performance liquid chromatography has been satisfactorily solved by the use of six-way valve. However, the sample loading technology of ordinary column chromatography or low-pressure column chromatography has been perplexing the majority of chromatographers. The technique of loading the sample is related to the success or failure of the separation of the sample components. Experienced chromatographers often use a dropper to quickly and evenly drop samples along the inner wall of the chromatographic tube, but it cannot completely guarantee that the sample solution entering the column packing bed will not diffuse severely and unevenly. The sample loading problem of inexperienced or...
