Abstract
The utility model provides a chromatographic column separation device for a laboratory. An external pressurization device and a decompression device are simultaneously used to enabling filling of a chromatographic column to be compact, so that the separation efficiency is high.
Description
Technical field
The utility model relates to a kind of device of chromatographic column, relates to particularly the indoor chromatographic column separator of a kind of experiment.
Background technology
Column chromatography claims again column chromatography.To fix and be loaded on mutually in post, mobile phase is liquid, and sample vertically from top to bottom moves and reaches separated chromatography.Column chromatography mainly for separating of, sometimes also play enrichment method effect.The key of column chromatography success or failure is: dress post is wanted closely, to require without tomography, seamless.The packing method of chromatographic column is divided into wet method dress post and dry column-packing, tight in order to make to fill post, generally adopt pressurization to carry out wet method dress post, when wet method filling chromatographic column, on chromatographic column top, connect a force (forcing) pump, by increasing pressure, make the filling of chromatographic column more tight.Decompression method is generally used for dry column-packing, conventional way connects a decompression air extractor in exit, chromatographic column bottom, then dried material to be loaded is added in chromatographic column, open decompression air extractor, now chromatographic column internal gas pressure reduces, dried material is promoted to decline by atmospheric pressure, makes material filling tight.In most cases, these two kinds conventional dress post means all can make chromatographic column filling tight, are convenient to the carrying out of separated and purifying work in laboratory work.Yet, if filler granularity is superfine, below 40 μ m, only use conventional method cannot accomplish that the filling of chromatographic column is tight, conventional efficient is extremely low.
Utility model content
The utility model overcomes the deficiencies in the prior art, provides a kind of experiment indoor chromatographic column separator, and this device utilizes external pressurized device and decompressor to make the filling of chromatographic column tightr simultaneously, and separative efficiency is higher.
The technical solution of the utility model is as follows:
A kind of separator of chromatographic column for laboratory, it is characterized in that described separator comprises chromatographic column 1, force (forcing) pump 2, liquid storage ball 3, decompression air extractor 4, buffer unit 5, force (forcing) pump 2 is arranged at the arrival end of liquid storage ball 3 tops, chromatographic column 1 is connected by liquid storage ball 3 with force (forcing) pump 2, decompression air extractor 4 is connected with the port of export of buffer unit 5, and chromatographic column 1 is connected by buffer unit 4 with decompression air extractor 3.
In the utility model, the material of chromatographic column 1 filling is the conventional parting material in laboratory, comprises one or more in silica gel, bonded silica gel, gel, macroreticular resin, polyamide, active carbon, aluminium oxide, diatomite, cellulose, ion exchange resin.
In the utility model, buffer unit 5 is any in bottle,suction, wide-mouth bottle, round-bottomed flask, boiling flask, conical flask.
The beneficial effects of the utility model: by increase a buffer unit (as a bottle,suction) between chromatographic column and decompression air extractor, can when filling post, wet method use decompressor and force (forcing) pump simultaneously, thereby make in chromatographic column material tightr, without tomography, seamless, the post effect of chromatographic column is higher, and filling time still less, dress post means are simple and convenient, can greatly improve the efficiency of laboratory chromatographic column separation.
Accompanying drawing explanation
Fig. 1 is the utility model overall structure schematic diagram
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further elaborated.
As shown in Figure 1, a kind of separator of chromatographic column for laboratory, comprise chromatographic column 1, force (forcing) pump 2, liquid storage ball 3, decompression air extractor 4, buffer unit 5, force (forcing) pump 2 is arranged at the arrival end of liquid storage ball 3 tops, chromatographic column 1 is connected by liquid storage ball 3 with force (forcing) pump 2, decompression air extractor 4 is connected with the port of export of buffer unit 5, and chromatographic column 1 is connected by buffer unit 4 with decompression air extractor 3.
While carrying out laboratory chromatography work, first use the eluant, eluent than fixing more approximately 1 times to be mixed into mutually homogenate shape with fixing, mixture is slowly poured into after chromatographic column, above chromatographic column, connect a liquid storage ball, in liquid storage ball, fill it up with eluant, eluent, connect above it force (forcing) pump.Meanwhile, in chromatographic column exit, by a buffer unit (as a bottle,suction), chromatographic column is connected with decompression air extractor.Open chromatographic column bottom piston, open force (forcing) pump and decompression air extractor simultaneously, by exceeding the fixedly eluant, eluent of phase in pillar, be discarded in buffer unit, treat that eluant, eluent liquid level approaches fixedly phase time, take off force (forcing) pump, close successively chromatographic column bottom piston and decompression air extractor, complete dress post process.In this chromatographic column, material is tightr, without tomography, seamless, and the post effect of chromatographic column is higher, and still less, dress post means are simple and convenient, can greatly improve the efficiency of laboratory chromatographic column separation for filling time.
