Abstract
The utility model relates to a liquid chromatogram determination system of water-soluble substances, which comprises a high-efficient liquid chromatogram and a water filter treatment system, wherein the water filter treatment system is connected with the high-efficient liquid chromatogram via a water delivery pipe and comprises a running water source, a filter device, a pure water manufacturing device, a water storage device and a flow rate control valve which are connected via a pipeline sequentially. The determination system can be operated automatically and continuously, is applicable to liquid chromatogram detection methods utilizing water as a mobile phase, and saves labor and force greatly.
Description
Technical field
The utility model belongs to the check and analysis technical field, is specifically related to a kind of liquid chromatogram measuring system of water-soluble substances.
Background technology
In the sample of liquid-phase chromatographic analysis, there are many samples to belong to water-soluble substances, as multiple water-soluble sugars such as glucose, sucrose, fructose.When measuring these water-soluble substanceses, some can only use pure water as moving phase.Liquid chromatography is higher to the purity requirement of water.At present, most laboratory adopts ultrapure water is loaded in the bottle, is connected with liquid chromatography, and there is certain shortcoming in operation like this, and the one, operation lacks robotization, need manually regularly change or add ultrapure water; The most important thing is failing in time to add under the situation of high purity water, will cause the process of damage or direct impact analysis testing the liquid chromatography instrument.
The utility model content
The purpose of this utility model is at prior art liquid chromatogram measuring system above shortcomings; provide a kind of ultrapure water that can provide continuously to be used for the detection system of liquid chromatography; be applied in the process of analyzing and testing of water-soluble substances (as glucose, sucrose, fructose, sorbierite etc.); make detecting operation more easily easy, what effectively guarantee to detect carries out smoothly and protect the liquid chromatography instrument to avoid damaging.
The utility model is achieved through the following technical solutions above-mentioned purpose:
A kind of liquid chromatogram measuring system of water-soluble substances, comprise the liquid chromatography instrument, it is characterized in that also comprising the water treatment system that links to each other by water-supply-pipe with the liquid chromatography instrument, described water treatment system comprises water source from the beginning, filtration unit, Water Purifiers, water storage device and the flowrate control valve that connects successively via pipeline.
The aperture of the filter core of filtrator is preferably 0.1 micron, on the filtrator multilayer filter core can be arranged, and water is effectively purified earlier entering Water Purifiers, reduces the burden of machine.
Described Water Purifiers preferably adopts MiliQ ultrapure water maker, and the water after MiliQ ultrapure water maker will be filtered is stored in the water storage device after purifying and becoming ultrapure water.Water storage device can adopt the conventional water receiver that is provided with intake-outlet, volume is preferably 3～5L, can play the effect of buffering water storage, and the water of depositing in the water storage device can prevent under the situation that accident is cut off the water, guarantee the stability of high performance liquid chromatography moving phase, the normal operation of safeguards system.Be provided with the pure water flowrate control valve between described water storage device and the liquid chromatography instrument, can pass through Flux Valve Control discharge or flow velocity, for example according to the concrete needs of detection commonly used, regulating flow rates is between 0.2mL/min～2mL/min.
The water source of system is a running water tap, is connected with pressure control valve on it, when high performance liquid chromatography moves, automatic control by operation valve, make tap water flow out, enter water storage device, to guarantee in the water storage device stable water yield being arranged through each layer filtration and ultrapure water maker.
Compared with prior art, the utlity model has following beneficial effect:
The utility model has solved the technical matters of the continuous water of check and analysis process, can guarantee that detection system carries out automatically continuously, need not manually to change ultrapure water, is applicable to water to be in the detection method of moving phase, has saved manpower and materials greatly.
System provided by the utility model is owing to have this device of water storage device, and the infringement that machine is caused during insufficient water in the time of can preventing from temporarily to cut off the water is in order to avoid testing can not be carried out smoothly.

Embodiment
Below further specify technical scheme of the present invention by specific embodiment.
Water swivel 1 outlet cut-in pressure operation valve 2 connects water pipe again, connects filtrator 3, contains 3 metafiltration cores in the filtrator, and the aperture is 0.1 micron; The water intake end that connects MiliQ ultrapure water maker 4 through the water pipe of filtrator again, the water side of MiliQ ultrapure water maker 4 directly is communicated with water receiver 5, the volume of water receiver is 3～5L, pure water inflow water collector 5 deposits, the water delivering orifice of water receiver 5 is provided with flowrate control valve 6, according to concrete detection needs, regulates discharge or flow velocity, when being applied to efficient liquid phase chromatographic analysis instrument 7 and detecting, the adjusting water flow velocity is 0.2～2mL/min.
When 7 operations of high performance liquid chromatograph device, water swivel 1 water outlet, after tap water becomes primary pure water through filtrator 3, become ultrapure water through MiliQ ultrapure water maker 4 again, entering water receiver 5 stores, the ultrapure water that is flowed out by water receiver 5 enters high performance liquid chromatograph device 7 after flowrate control valve 6 is regulated flow, become one of source of its moving phase.
