Description
technical field
The utility model relates to the column chromatography combination unit that the adjustable column temperature of a kind of efficient dress post can freely break, and belongs to technical field of chemical.
Background technology
Column chromatography (Column chromatography) claim again column chromatography, is a kind of distribution method taking partition equilibrium as mechanism.The principle of column chromatography is the same with thin-layer chromatography, paper chromatography, gas-chromatography and high performance liquid chromatography etc., utilize absorption or the difference of solubility property (distributing) or the difference of other affinity interaction performance of each component in a certain material in mixture, make the flow of solution of mixture through this kind of material, carry out the effect such as absorption or distribution repeatedly, thereby component is separated.Column chromatography mainly for separating of, sometimes also play enrichment method effect.Chromatogram system comprises two phases, and one is fixing phase, and one is mobile phase.Fixing being loaded on mutually in post, mobile phase is liquid, and sample vertically from top to bottom moves, and in the time of two-phase relative motion, the repeated multiple times difference of utilizing contained each component partition equilibrium character in mixture, finally reaches object separated from one another.
Column chromatography is conventionally divided into adsorpting column chromatogram and distributes column chromatography two classes.The conventional aluminium oxide of adsorpting column chromatogram and the silica gel phase that fixes.Distributing in column chromatography using silica gel, diatomite and cellulose as supporting agent, to absorb the relatively large liquid phase that fixes, and supporting agent itself does not play centrifugation.
Conventionally in glass tube, insert surface area very large, make it to become column through the porous of overactivation or powdery solid adsorbent, such tubulose post is called adsorption chromatography post.The method that uses adsorption chromatography post separating mixture, is called adsorpting column chromatogram.This method can be used for separating most of organic compounds, is particularly suitable for the separation of complicated natural products.Separation capacity is level from several milligrams to hundred milligrams, so, be applicable to separate and refining relatively large sample.Adsorpting column chromatogram conventionally in glass tube, insert surface area very large, through porous or the powdery solid adsorbent of overactivation.In the time that mixture solution to be separated flows through adsorption column, various compositions are attracted to the upper end of post simultaneously.When eluent stream lower time, due to different compound adsorption capacity differences, down the speed of wash-out is also different, so formed different levels, be solute in post from top to bottom by adsorbent affinity size is formed respectively to some colour bands, then the solute having separated during with solvent elution can wash out respectively collection from post; Or post is blotted, after extruding, separate by colour band, the solute in each colour band being extracted with solvent.For on post, do not develop the color compound separation time, can check with the fluorescence presenting after UV-irradiation, or in the time using solvent elution, collect respectively eluent and identified one by one.
The glass tube that is used for loading adsorbent in above-mentioned is chromatotube, chromatotube be internal diameter evenly, the horminess glass tube of lower end reducing, lower end is plugged with cotton or is equipped with core.
At present, known column chromatography chromatogram pipe is integral type, and its column volume is fixed, and causes the useful load upper limit of mutually fixing and mobile phase unadjustable.And the column volume of chromatotube and the loading of fixing phase can directly affect post and imitate, and then affect the separating effect of separated sample.The loading of fixing phase, depending on separated sample size and experiment purpose, is generally 30 to 40 times of separated sample size, can increase to 100 times while needs, differs greatly.Therefore, the chromatotube column volume specification of choosing in experimentation depends on the loading of fixing phase, and this has just caused the utilization rate of the fixing traditional chromatotube of specification not high, not only affects conventional efficient, has also caused the idle and waste of resource.And the material of chromatotube is glass, the contour structures of integral type causes it, and in use somewhere is chipping, and chromatotube cannot continue to use.The more important thing is, column chromatography requires high to the operational quality of dress post and application of sample, and the chromatographic column installing answers filling even, degree of tightness is suitable consistent, there is no bubble and crack, otherwise can cause eluant, eluent to flow irregular and form " channel ", cause chromatographic band distortion, affect separating effect.What when application of sample, require that sample concentrates as far as possible adds, and after must will be dried solid sample to be separated weighing, is dissolved in and in the solvent that polarity is as far as possible little, makes it to become concentrated solution, is carefully added to equably capital along chromatographic column tube wall with dropper.After adding, container and dropper rinsed clean and be all added in post with a small amount of solvent, then going down with the sample solution drip washing that solvent handle sticks on tube wall.If application of sample is inhomogeneous, can cause colour band to intersect, affect separating effect.The elongated profile of tradition chromatotube has determined the large and not easy cleaning of chromatotube inwall of its dress post, application of sample operation easier, and the length of chromatotube is longer, internal diameter is less, and dress post, application of sample operation easier are larger, and chromatotube inwall is more difficult cleaning also.In addition, column temperature is not suitable for affecting separating effect, carries out at normal temperatures uncontrollable column temperature and use traditional integral type chromatotube to carry out column chromatography experiment.
