Initialize the control system of liquid-level tracking device, and the data of host computer are received by communication module, to motor
M2, motor M3, motor M4 provide drive signal, make three shaft mechanical arms run to the test tube position specified, and control system is made on Z arms
Slide block 15 declines, operation in the middle of slide block carry injection needle 8 encounter liquid level when, liquid level sensor send a level signal to
Controller.
Controller receives this signal, and control syringe pump 1 extracts liquid, and adjusts the speed that injection needle declines on Z axis
Degree, is allowed to be consistent with liquid level decrease speed, realizes that liquid level is followed.
When syringe pump is drawn into the set amount of experiment, can to controller one complete signal, then move in control slide block, it is sliding
Block drives injection needle pull-up and control machinery arm runs to specified SPE posts position, then controls Z arm top shoes and move down, so that injection
Pin declines the aperture at insertion SPE Zhu Zhugai centers, when the sealing ring at the injection needle step withstands the aperture on lid, syringe pump
The liquid that injection has just been drawn from test tube.

Air is carried out extracting for power source and then boosting, if laboratory has nitrogen, as long as accessing nitrogen（Nitrogen has in itself
Pressure, need not be by injecting pumping）.
Syringe pump also connects pure water or ethanol by the first solenoid directional control valve 2, because the liquid of suction does not enter syringe pump
（If entering membership causes cross-contamination）, liquid only can reach the 3rd solenoid directional control valve before in liquid storage pipe 3（Syringe pump is once inhaled
It is 10ML to enter amount, is had between injection needle and three tunnel switching valves>The liquid storage pipe of 10ml is depositing the liquid of suction）If inhaling
The liquid for entering does not enter syringe pump, then syringe pump because of the reciprocating motion that do not have medium can shorten injection in shell in suction
The life-span of pump, therefore syringe pump can access pure water or ethanol by the first solenoid directional control valve 2, help aspirate, play lubrication
Effect.
Due to there is large particulate matter in the liquid that some are tested, to the injection of SPE posts, flow rate of liquid is too fast may cause SPE
Post is blocked, so adding pressure transducer 4 in the duct, when pressure exceedes setting value, instrument is returned by pressure transducer 4
Signal is reported to the police, and reaches safe handling device（Or instrument）Purpose.
In this utility model, due to by making liquid, gas are implanted sequentially in the liquid storage pipe between syringe pump and injection needle
And solution, liquid and solution are separated using gas, solution is not entered syringe pump and is only temporarily stored in liquid storage pipe, and store up
Liquid pipe is easy to be cleaned using liquid or gas, therefore avoids cross infection.
Above in association with accompanying drawing, operation principle of the present utility model is described in detail.But one of ordinary skill in the art
