Abstract
The utility model relates to a high efficiency liquid-phase chromatographic pole, having a general liquid-phase chromatographic pole. The utility model is characterized in that the both ends of the general liquid-phase chromatographic pole are respectively added with a magnetic field, namely the both ends of the general liquid-phase chromatographic pole are wound with a limited turn number of coils (2) whose both ends are connected to a direct-current power supply (3), and the both ends of the general liquid-phase chromatographic pole can also be respectively added with a permanent magnet (4). The utility model has high separation efficiency which is six timers higher than that of the general liquid-phase chromatographic pole.
Description
The utility model relates to a kind of tripping device that uses in the liquid chromatography separation.
Liquid phase chromatography is a kind of separation method, uses chromatographic column during separate substance.Existing chromatographic column generally is made of the material that stainless-steel tube or plastic tube or glass tube are wherein filled so that centrifugation to be arranged, and also useful kapillary is made.These have the material of centrifugation and tube wall to constitute stationary phase, and liquid is moving phase, two contact and when doing relative motion in the sample each component different with the acting force between the two-phase, and with its separation.Here said acting force may be from effects such as suction-operated, distributional effects, ion exchange or molecular sieve.The physical property of being filled in the effect of separating and the chromatographic column is relevant, also relevant with the number of ideal plates of these materials formations.But select these experiment conditions in any case, carry out liquid chromatography by existing chromatographic column and separate, the raising of its efficient all is limited.
The purpose of this utility model is to provide a kind of performance liquid chromatographic column, from the liquid phase separation material separation efficiency is significantly improved with it, can remedy above-mentioned deficiency of the prior art.
The purpose of this utility model is achieved in that at existing liquid-phase chromatographic column and comprises that the two ends of chromatography chromatographic column, adsorption chromatography post, distribution chromatography post, ion-exchange chromatography, gel chromatographic columns add a magnetic field, promptly twine the coil of 2～400 numbers of turn at the two ends of existing liquid-phase chromatographic column, two of this coil terminates on the direct supply, also can respectively add a permanent magnet at the two ends of common liquid-phase chromatographic column.
The utility model and existing chromatographic column compare, and separation efficiency has improved 5 times.
Accompanying drawing 1 is the structural representation of an embodiment of the present utility model.
Accompanying drawing 2 is structural representations of another embodiment of the present utility model.
1 common chromatographic column in the accompanying drawing, 2 coils, 3 DC voltage-stablized source apparatus, 4 permanent magnets.
In one embodiment, add the inductive coil (2) of certain number of turn at the two ends of common liquid-phase chromatographic column (1), these coil two ends respectively connect DC voltage-stablized source apparatus (3).In another embodiment, respectively add a permanent magnet (4) at the two ends of common liquid-phase chromatographic column (1), its magnetic induction density can be selected arbitrarily.
To the adsorption chromatography post, can make shell with permanent magnet.
Claims (1)
1, a kind of performance liquid chromatographic column, it comprises an existing liquid-phase chromatographic column (1), it is characterized in that adding a magnetic field at the two ends of this existing liquid-phase chromatographic column (1), promptly twine the coil (2) of 2～400 numbers of turn at existing liquid-phase chromatographic column (1) two ends, two of this coil (2) terminates on the direct supply (3); Also can respectively add a permanent magnet (4) at the two ends of common liquid-phase chromatographic column (1).
