Abstract
The utility model relates to an analysis and detection instrument for chemical substances, and particularly relates to a liquid chromatograph. The liquid chromatograph comprises a liquid container, a liquid feeding device and a detection device, wherein a liquid suction pipe of the liquid feeding device is communicated with an inner cavity of the liquid container through a pipeline; a liquid outlet pipe of the liquid feeding device is communicated with a liquid inlet pipe of the detection device. The liquid chromatograph is characterized in that the liquid feeding device comprises a housing, two sealing covers fixedly connected with the interior of the housing through a bracket, and a rotatable quantitative tube clamped arranged between the two sealing covers; the quantitative tube is in a shape of a sealing housing. With the structure, the liquid chromatograph disclosed by the utility model is provided with an automatic liquid inlet device, manpower is replaced, the stability is relatively high, the liquid inlet efficiency is improved, and the detection cost is reduced, so that the detection result is relatively accurate.
Description
Technical field
The utility model relates to a kind of chemical substance analysis and detecting instrument, specifically a kind of liquid chromatograph.
Background technology
Chromatograph is the device that carries out stratographic analysis, be widely used in detection, analysis and the data recording of chemical products, chromatograph comprises liquid chromatograph and gas chromatograph, liquid chromatograph is generally used for the chemical substance that detects solution state, existing chromatograph does not have ad hoc automatic liquid inlet aspect feed liquor, generally by artificial, with syringe, by injection port, injected, this feed liquor mode efficiency is low, waste a large amount of manpowers, and solution is also unstable in feed liquor process, causes the deviation in detection.
Summary of the invention
The utility model provides a kind of automatic feed liquor, liquid chromatograph that efficiency is higher for addressing the above problem.
The utility model is that the technical scheme that technical solution problem adopts is:
A kind of liquid chromatograph, comprise and put liquid container, liquid feeding device and pick-up unit, the pipette of described liquid feeding device is by pipeline and put liquid container intracavity inter-connection, the drain pipe of described liquid feeding device is connected with the feed tube of pick-up unit, it is characterized in that: described liquid feeding device comprises housing, by support, be fixedly connected on two cappings and the rotatable quantity tube being installed between two cappings in housing, described quantity tube is the housing shape of sealing, and the two ends of quantity tube are respectively equipped with inlet opening and the fluid hole of eccentric setting, described inlet opening and fluid hole are coaxially set, described pipette and liquid pushing tube are inserted to respectively in the capping at quantity tube two ends, described pipette and liquid pushing tube plug-in mounting position are symmetrical arranged centered by the axis of quantity tube, the outside suit follower gear of described quantity tube, separately have on the output shaft that is arranged on the stepper motor in housing and be set with driving gear, described follower gear is meshed with driving gear.
Owing to having adopted said structure, a kind of liquid chromatograph described in the utility model is provided with automatic liquid inlet, replaces manually, and stability is higher, has improved feed liquor efficiency, reduces testing cost, makes testing result more accurate.
Accompanying drawing explanation
Fig. 1 is the structural representation of an embodiment of the utility model.
Fig. 2 is the structural representation of liquid feeding device.
Embodiment
As shown in the figure, a kind of liquid chromatograph described in the utility model, comprise and put liquid container 1, liquid feeding device and pick-up unit 2, the described liquid container 1 of putting is provided with a plurality of, the different solution of difference splendid attire, the pipette 6 of described liquid feeding device is by pipeline and put liquid container 1 intracavity inter-connection, multiple solution is mixed in pipette 6, the drain pipe 7 of described liquid feeding device is connected with the feed tube of pick-up unit 2, described liquid feeding device comprises housing 3, by support, be fixedly connected on two cappings 5 and the rotatable quantity tube 4 being installed between two cappings 5 in housing 3, described pipette 6 and drain pipe 7 are communicated to respectively in housing 3, the housing shape that described quantity tube 4 is sealing, and the two ends of quantity tube 4 are respectively equipped with inlet opening and the fluid hole of eccentric setting, described inlet opening and fluid hole are separately positioned on the sidewall at quantity tube 4 two ends, and the intracavity inter-connection of inlet opening and fluid hole and quantity tube 4, described inlet opening and fluid hole are coaxially set, described pipette 6 and liquid pushing tube 7 are inserted to respectively in the capping 5 at quantity tube 4 two ends, the sidewall at described quantity tube 4 two ends is fitted in respectively the inner side of two cappings 5, prevent that the solution in quantity tube 4 from flowing out, described pipette 6 and liquid pushing tube 7 plug-in mounting positions are symmetrical arranged centered by the axis of quantity tube 4, the outside suit follower gear 10 of described quantity tube 4, separately have on the output shaft of the stepper motor 8 being arranged in housing 3 and be set with driving gear 9, described follower gear 10 is meshed with driving gear 9, described stepper motor 8 can drive quantity tube 4 rotations, therefore, when pipette 6 is connected with inlet opening, fluid hole is not communicated with liquid pushing tube 7, solution enters in quantity tube 4, when reaching a certain amount of, stepper motor 8 drives quantity tube 4 rotations, when fluid hole is connected with liquid pushing tube 7, pipette 6 is not communicated with inlet opening, quantitative solution is discharged by fluid hole, make liquid feeding device can realize quantitative liquor charging.
