Description
Technical field
The utility model is specifically related to a kind of key-course analysis apparatus automatically, belongs to organic compound equipment for purifying.
Background technology
The multi-component materials such as fine chemical product, natural products and Chinese medicine need separation and purification, and the general chromatographic column that adopts is purified.Traditional chromatographic column comprises device for storing liquid and chromatographic column two parts.Chromatographic column lower floor filling Stationary liquid, be generally silica gel, upper strata fills material to be separated, configures suitable mobile phase and pours in device for storing liquid and carry out wash-out.When using such device, operating personnel need keep a close eye on device for storing liquid liquid level situation, supplement mobile phase in time.This just makes the workload of operating personnel increase, and slightly neglects the phenomenon that just there will be sky, badly influences separative efficiency.
Utility model content
The purpose of this utility model is to provide a kind ofly can supplement mobile phase automatically, prevent the automatic key-course analysis apparatus that chromatographic column is dry and cracked, reduce operating personnel's workload, increase work efficiency.
The technical solution of the utility model is: a kind of key-course analysis apparatus automatically, comprise chromatographic column and device for storing liquid, it is characterized in that: also comprise Agitation Tank, solvent pump, U-tube, photoelectric liquid level sensor and relay, Agitation Tank is connected with solvent pump, solvent pump is connected with device for storing liquid, is communicated with respectively bottom device for storing liquid with chromatographic column with one end of U-tube; The U-tube other end is vertically fixing and it is highly more than or equal to device for storing liquid overhead height; Described photoelectric liquid level sensor comprises low photoelectric liquid level sensor and high photoelectric liquid level sensor, is all arranged in U-tube; Relay comprises low level relay and high-order relay, respectively with low photoelectric liquid level sensor and high photoelectric liquid level sensor wired connection; High-order relay is connected solvent pump with low level relay by bigeminy dual control.
Described low photoelectric liquid level sensor and high photoelectric liquid level sensor are connected on the outer tube wall of U-tube.
The setting height(from bottom) of described low photoelectric liquid level sensor is the 1/10-1/6 to overhead height bottom device for storing liquid.To avoid device for storing liquid stream during pump work empty.
The setting height(from bottom) of high photoelectric liquid level sensor is the 1/2-2/3 to overhead height bottom device for storing liquid.The too high solution that causes of solution height is avoided to overflow.
Described U-tube is glass material.
The utility model compared with prior art, has the following advantages and technique effect:
1, operating personnel's workload is alleviated;
2, effectively prevent owing to lacking the chromatographic column that mobile phase causes dry and cracked, thus improve separative efficiency.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model embodiment is described in detail.
See Fig. 1, this automatic key-course analysis apparatus comprises Agitation Tank 1, solvent pump 2, device for storing liquid 3, U-tube 4, low photoelectric liquid level sensor 5, high photoelectric liquid level sensor 6, low level relay 7, high-order relay 8 and chromatographic column 9, Agitation Tank 1 is connected with solvent pump 2, and solvent pump 2 is connected with device for storing liquid 3.Device for storing liquid 3 is cylindrical shape, laterally installs; Be provided with the fluid hole 10 be communicated with chromatographic column 9 bottom device for storing liquid 3, and between fluid hole 10 and chromatographic column 9, flow control valve 11 be installed, with coutroi velocity.Be communicated with bottom device for storing liquid 3 by U-tube 4 left end, right-hand member is vertically fixing and it highly equals device for storing liquid 3 overhead height; Low photoelectric liquid level sensor 5 and high photoelectric liquid level sensor 6 are arranged in U-tube 4, and the setting height(from bottom) of low photoelectric liquid level sensor 5 and high photoelectric liquid level sensor 6 is respectively to overhead height bottom device for storing liquid 3 1/5 and 2/3.
Low level relay 7 and high-order relay 8 respectively with low photoelectric liquid level sensor 5 and high photoelectric liquid level sensor 6 wired connection; Low level relay 7 is connected solvent pump 2 with high-order relay 8 by bigeminy dual control.
During use, install chromatographic column filler and sample to be separated; Suitable mobile phase is prepared in Agitation Tank 1.Turn on the power switch, low photoelectric liquid level sensor 5 senses no liquid in U-tube 4, and send signal input low level relay 7, low level relay 7 action, solvent pump 2 is started working, and is pumped into by mobile phase in device for storing liquid 3; When liquid level reaches the height at high photoelectric liquid level sensor 6 place, high photoelectric liquid level sensor 6 senses liquid in U-tube 4, and send signal and input high-order relay 8, the action of high-order relay 8, solvent pump 2 quits work.Along with wash-out carries out, in device for storing liquid 3, liquid level drops to low level, and low photoelectric liquid level sensor 6 senses no liquid in U-tube 4, and send signal input low level relay 7, low level relay 7 action, solvent pump 2 is started working, and is pumped into by mobile phase in device for storing liquid 3.Go round and begin again, thus realize automatically controlling.
Above embodiment has made comparatively detailed description to the utility model; but these descriptions are not to restriction of the present utility model, protection domain of the present utility model comprises those apparent conversion or alternative and remodeling to those skilled in the art.
