Abstract

The utility model provides a low-pressure liquid chromatography separator, which comprises a liquid storage tank (4) and a chromatography column (5), the chromatography column (5) is connected and communicated with the liquid storage tank (4), the chromatography column (5) is filled with a fixing phase (6) internally, the liquid storage tank (4) is equipped with a gas inlet (3) with a valve (2), the gas inlet (3) is connected with the gas supply system through the valve (2), sealing caps (1,7) made of materials a syringe needle can pierce through are arranged on the top of the liquid storage tank (4). The device works under the low pulse pressure, the velocity of flow phase through the chromatography column fixing phase is greatly increased, and the separation speed is improved, thereby effectively solving the bubble problem in resin bed. The device can get higher column effects, faster separation speed, and longer service life of chromatography column.

Description

A kind of low pressure liquid chromatography tripping device
Technical field
The utility model belongs to the analytical chemistry field, is specifically related to a kind of low pressure liquid chromatography tripping device.
Background technology
The moving phase of classical liquid chromatography only relies on action of gravity, and by the chromatographic column stationary phase, velocity of separation is slow from top to bottom, and a separation cycle needs several hours to tens hours.In addition, the resin bed of classical chromatographic column should be covered by solution fully, forbids having bubble to exist in the bed, sneaks into if any bubble, and then the post of chromatographic column is imitated and altered a great deal, and is difficult to get rid of, and generally need adorn post again, and this influences the life-span of chromatographic column.
Summary of the invention
The purpose of this utility model is at the existing defective of classical liquid chromatography, and a kind of new quick, efficient, economic low pressure liquid chromatography tripping device is provided.
A kind of low pressure liquid chromatography tripping device, the reservoir (4) and the chromatographic column (5) that comprise contain fluid, chromatographic column (5) is connected with reservoir (4) and communicates, fill stationary phase (6) in the chromatographic column (5), it is characterized in that: establish gas inlet port (3) on the reservoir (4), gas inlet port (3) is provided with valve (2), and air intake opening (3) links to each other with air supply system by valve (2), and reservoir (4) top is provided with the gland bonnet (1,7) that the material that can pass with syringe needle is made.The length of chromatographic column is 150mm~300mm, and internal diameter is 2.5mm~6mm, and working pressure is 0.1Mpa~0.5Mpa.
When advantage of the present utility model is to use this equipment, the gas persistent pressure, sample or eluent pass reservoir top seal lid with syringe, add reservoir, and each adding is preceding by gas emptying chromatographic column.This device is operated under the pulse low-pressure state, and moving phase is accelerated greatly by the speed of chromatographic column stationary phase, and velocity of separation is improved.In addition, by the pressure emptying, can solve air bubble problem in the resin bed effectively.Use this device, can obtain that higher post is imitated, velocity of separation, long chromatographic column life-span faster.
Description of drawings
Fig. 1 is a kind of structural representation of low-pressure chromatography tripping device.
Fig. 2 is the structural representation of another kind of low-pressure chromatography tripping device.
Among the figure, 1-silica gel plug, 2-valve, 3-gas inlet port, 4-reservoir, 5-chromatographic column, 6-stationary phase, 7-silica gel lid.
Embodiment
Below in conjunction with embodiment technical scheme of the present invention is further elaborated.
Embodiment 1
As shown in Figure 1, a kind of low pressure liquid chromatography tripping device comprises the reservoir 4 and the chromatographic column 5 of contain fluid, and chromatographic column 5 is connected with reservoir 4 and communicates.Fill stationary phase 6 in the chromatographic column 5.Establish gas inlet port 3 on reservoir 4, establish valve 2 on the gas inlet port 3, gas inlet port 3 links to each other with air supply system by valve 2, and reservoir 4 tops seal with silica gel plug 1.
The length of chromatographic column 5 is 150mm~300mm, and internal diameter is 2.5mm~6mm, and working pressure is 0.1Mpa~0.5Mpa, can select arbitrarily in scope.In the present embodiment, root chromatogram column length is 250mm, and internal diameter is 4mm, and working pressure is 0.2Mpa.
Embodiment 2
As shown in Figure 2, another kind of low pressure liquid chromatography tripping device, structure is similar with embodiment 1, and difference is on reservoir 4 tops with 7 sealings of silica gel lid.
