On the basis of technique scheme, described gas-liquid separation bottle 2 is a cuboid, and material adopts transparent glass or plastics or resin, and this design can make the light sensor 3 better variations that must detect gas-liquid separation bottle 2 light-conductive rates, and it is disconnected to reduce erroneous judgement.
On the basis of technique scheme, the end of the imbibition pipe fitting in described mobile phase fluid reservoir 1 inner chamber is enclosed with filtrate cover 11.
On the basis of technique scheme, the described phase pretreatment unit that automatically flows also comprises a calandria 12, and calandria 12 is affixed in the outside of hermetically sealed can 6 and with external power source and communicates, and calandria 12 adopts the PTC thermo-sensitive materials.
Further, the described phase pretreatment unit that flows automatically also comprises a housing 13, and these all parts of phase pretreatment unit that flow automatically remove the phase fluid reservoir 1 that flows and all are positioned among the housing 13.
Present embodiment concrete steps in use is as follows:
1) will flow and pour into mutually in the phase fluid reservoir 1 that flows, connect power supply behind the jam-pack sealing-plug 1-1;
2) light sensor 3 is started working, detect the light-conductive rate of gas-liquid separation bottle 2, there is not the phase of flowing during because of original state in the gas-liquid separation bottle 3, so signal of light sensor 3 outputs, it is inlet end 4-1 and the outlet side B4-3 vavuum pump A5 operation simultaneously that communicates that three-way magnetic valve A4 enters "on" position, and the air in the gas-liquid separation bottle 2 is discharged;
3) form negative pressure in the gas-liquid separation bottle 2, mobilely in the gas-liquid separation bottle 2 the gas existence is arranged in mutually if flow to be entered by mobile phase fluid reservoir 1, then gas climbs away mobile phase under the effect of gravity, thereby reaches the purpose of gas-liquid separation;
4) liquid level constantly raises in the gas-liquid separation bottle 2, when being elevated to the detection level face of light sensor 3, the light-conductive rate of the mobile phase of cause is different with the light-conductive rate of air, so light sensor 3 can detect the variation of light-conductive rate, signal of output after time-delay a period of time, vavuum pump A5 quits work, three-way magnetic valve A4 enters off-position, and to be that outlet side A4-2 and outlet side B4-3 communicate obstructed between outlet side and the inlet end 4-1, this installs external high pressure constant-flux pump and starts working, and flowing in the gas-liquid separation bottle 2 enters deaeration pipe 7 mutually;
If in flowing mutually bubble is arranged, liquid level after a period of time in the gas-liquid separation bottle 2 can descend, when dropping to the detection level face of light sensor 3, signal of light sensor 3 outputs, vavuum pump A5 starts working, and is faster than the rate of liquid aspiration of high pressure constant-flux pump because of the gettering rate of vavuum pump A5, forms negative pressure so understand in the gas-liquid separation bottle 2, mobile phase is entered in the gas-liquid separation bottle 2, so repeatedly by mobile phase fluid reservoir 1 again;
5) atmospheric pressure value in the B/P EGR Back Pressure Transducer EGR 9 measurement hermetically sealed cans 6, if this value greater than lower limit set value then B/P EGR Back Pressure Transducer EGR 9 send a signal controlling vavuum pump B8 and start working, vavuum pump B8 discharges the gas in the hermetically sealed can 6 by check valve 10, atmospheric pressure value in the hermetically sealed can 6 begins to descend, atmospheric pressure value can reach lower limit set value after a period of time, this moment, B/P EGR Back Pressure Transducer EGR 9 was exported a signal once more, this signal controlling vavuum pump B8 quits work, check valve 10 is also closed thereupon, and be negative pressure state this moment in the hermetically sealed can 6;
6) the mobile deaeration pipe 7 of flowing through mutually, because of having the characteristic of gas-permeable, liquid-impermeable because of degassing pipeline 7 adopts the Teflon material again for negative pressure state in the hermetically sealed can 6, so the gas that is dissolved in the liquid is separated out in the inner chamber that enters hermetically sealed can 6, flowing after handling then enters in the high pressure constant-flux pump mutually;
If have in flowing mutually dissolved gas then gas can constantly separate out and enter in the hermetically sealed can 6, so the atmospheric pressure value in the hermetically sealed can 6 can constantly raise, signal of B/P EGR Back Pressure Transducer EGR 9 outputs when being elevated to upper limit set value, this signal controlling vavuum pump B8 starts working, vavuum pump B8 discharges gas by check valve 10, atmospheric pressure value in the hermetically sealed can 6 begins to descend, atmospheric pressure value can reach lower limit set value after a period of time, this moment, B/P EGR Back Pressure Transducer EGR 9 was exported a signal once more, this signal controlling vavuum pump B8 quits work, check valve 10 is also closed thereupon, and once more become negative pressure state in the hermetically sealed can 6 this moment, so repeatedly;
7) mobile entering mutually in the high pressure constant-flux pump is by going out the operation of high pressure constant-flux pump output carrying out chromatography experiment;
When 8) entering gas because of some unknowable reasons as if the high pressure constant-flux pump, just need carry out exhaust work, need make the fluid termination non-resistance pipeline of high pressure constant-flux pump and make three-way magnetic valve A4 enter off-position this moment, vavuum pump A5 starts working and sucks outside air and be pressed in the phase fluid reservoir 1 that flows, mobile in the phase fluid reservoir 1 of flowing met to be introduced into and carried out entering after the gas-liquid separation deaeration pipe 7 in the gas-liquid separation bottle 2 and finish the degassing and handle, enter at last in the high pressure constant-flux pump, because of the outlet end place of high pressure constant-flux pump not having pressure, so the bubble in the high pressure constant-flux pump can flow out mutually together along with flowing, and finishes exhaust process;
Finish until experiment so repeatedly.
The utility model is not limited to above-mentioned embodiment, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, all fall within the protection domain of the present utility model.
