Abstract
The utility model provides a low-pressure liquid-phase chromatogram separating device, comprising a liquid flume that is used for containing liquid and at least two chromatogram columns. Each chromatogram column is connected with a bottom canal of the liquid flume. An air or liquid inlet is arranged on the upper part of the liquid flume, and the air or liquid inlet is connected with an air-feeding system or a stuff-feeding system through a valve. The device can realize a half-automatization of the chromatogram separating process, which is good for the big-scale industrial application.
Description
Technical field
The utility model belongs to the analytical chemistry field, is specifically related to the 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, does not allow bubble in the bed and exists, and sneaks into if any bubble, can cause that the post of chromatographic column is imitated great changes, and be difficult to get rid of, and generally need adorn post again, thereby influence the life-span of chromatographic column.
Also have, the reservoir of classical liquid chromatography tripping device has only several milliliters, for the single-column operation, can not realize continuous drip washing and regeneration, can not realize quick separation and concentration, and it is more time-consuming to operate, and is difficult for realizing the large-scale industrialization application.
Summary of the invention
The purpose of this utility model is at the existing defective of classical liquid chromatography tripping device, and a kind of quick, efficient, economic low pressure liquid chromatography tripping device is provided.
Low pressure liquid chromatography tripping device provided by the utility model, the reservoir and the chromatographic column that comprise contain fluid, fill stationary phase in the chromatographic column, its number is at least 2, the bottom of reservoir is provided with at least 2 conduits that have valve, each chromatographic column is connected with the conduit ground, establishes gas or liquid inlet on reservoir top, and described gas or liquid inlet link to each other with air supply system or feeder system by valve.
The number of chromatographic column is decided according to need.
Gas and liquid inlet can be a passage, also can separately be set to two independently passages.
During actual the use, reservoir generally is divided into drip washing reservoir and regeneration reservoir, uses separately.
In addition, the length of chromatographic column is 150mm～300mm, and internal diameter is 2.5mm～6mm, and working pressure is 0.1MPa～0.5MPa.
When using this equipment, two kinds of operations of application of sample drip washing and column regeneration are arranged.During application of sample drip washing, operation as follows: close all valves of reservoir bottom conduit, in reservoir, add an amount of eluent.Sample low pressure upper prop links to each other chromatographic column one by one with reservoir bottom conduit, open gas inlet port valve, pressurization, the valve of unlatching reservoir bottom conduit, beginning drip washing.During column regeneration, the chromatographic column that needs are regenerated links to each other with the reservoir that regenerated liquid is housed, and method of operating is the same.
This device is operated under the 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.Because the volume of reservoir strengthens, need not repeatedly add leacheate or regenerated liquid, only need just can control the process of separation or column regeneration, realize the semi-automation of chromatographic resolution work easily, be beneficial to large-scale commercial Application according to the solution amount that flows out chromatographic column.Therefore, low pressure liquid chromatography tripping device provided by the utility model is a kind of quick, efficient, economic liquid chromatography tripping device.
