Description
Technical field
The utility model relates to technical field of experiment equipment, and in particular to a kind of plus-minus pressure chromatographic column.
Background technique
Chromatographic column is generally simple glass pipe or lucite tube, and stationary phase and mobile phase will be according to the differences of separation object
Do different selections.According to distribution coefficient of each component in sample mixture in stationary phase (filler) and mobile phase (eluant, eluent)
Difference, by repeatedly distributing a kind of method for separating component repeatedly.Common chromatography column due to not plus depressurization,
So that separating rate is slower, mask work efficiency is very low.It does not install the piston of adjustable fluid flow additional, not can control tape transport speed
Degree, causes liquid layered bad, cannot reach best separating effect.And it is easy when configuring column chromatography stationary phase
There is bubble generation, to keep stationary phase uneven, influences separating effect when elution samples.In addition in the operation of experiment
Cheng Zhong often duplicates the operation of sample inefficient, easy to pollute.It only leans on the manual operation of experimenter cumbersome time-consuming and repeatedly opens
Lid is loaded sample easy to pollute manually, is unfavorable for isolating and purifying for sample.
Utility model content
Purpose of the utility model is to overcome the above-mentioned shortcomings and provide a kind of plus-minuss to press chromatographic column, practical, operation
Simply, using positive/negative-pressure double-purpose vacuum pump, decompression excludes bubble when realizing the chromatography column packing, and pressurization makes eluant, eluent when elution
The function of stationary phase can be passed through, the addition number of sample and eluant, eluent is reduced, improves control efficiency, raising isolates and purifies
Effect.
Purpose of the utility model is realized as follows:
A kind of plus-minus pressure chromatographic column, including column body and lower prop, the column body top are equipped with sealing cover, the sealing
It covers and is equipped with sample-adding pipe and bleeding point, the lower end of the sample-adding pipe is switched equipped with controllable flow rate, and upper end is equipped with charging hopper, described
Bleeding point connection plus-minus pressure double-purpose vacuum pump, the side wall of the column body are equipped with filling opening, and the filling opening connects liquid storage ball, institute
The upper end for stating liquid storage ball is equipped with addition funnel, is equipped with step in the lower prop, and the step is equipped with filter device, it is described on
Cylinder is clamped in bracket, and the bottom of the bracket is equipped with vibrator.
Preferably, the sample-adding pipe is standard cylinder, and tube wall is equipped with scale.
Preferably, ground is equipped between the column body and lower prop.
Preferably, the bottom of the lower prop is equipped with outlet valve.
Preferably, the filter device includes sand core fixed ring and sand core, and the sand core is located at the inside of sand core fixed ring,
The sand core fixed ring is stuck on step.
Preferably, the sand core is one of glass sand core, filter cloth, stainless steel filtering net, polytetrafluoroethylene diaphragm.
The beneficial effects of the utility model are:
The utility model is practical, easy to operate, using positive/negative-pressure double-purpose vacuum pump, when realizing the chromatography column packing
Decompression excludes bubble, and pressurization allows eluant, eluent to pass through the function of stationary phase when elution, reduces adding for sample and eluant, eluent
Add number, improve control efficiency, raising isolates and purifies effect.
