Background technology
The laboratory is in to fluid sample during the persistent organism enrichment, often can use the microanalysis filtration unit, this device comprises liquid storage bottle, filtrator and receiving bottle, when suspended particulate substance is more in the fluid sample, cause easily filter membrane to stop up, therefore filtrator needs the frequent filter membrane, and the experimenter has to outwell the sample in the liquid storage bottle, has wasted greatly sample; Above-mentioned filtrator comprises glass funnel and the filter plate that matches with this funnel in addition, during filtration, puts glass fiber filter on the filter plate upper berth, and fluid sample is penetrated in the funnel by filter plate by membrane filtration, then enters in the receiving vessel.Above its defective of filtrator is: sample solution very easily stops up filter membrane and filter plate when filtering, filter velocity is slowed down, and filtration efficiency is low.This filtrator does not arrange enriching apparatus in addition, only can filter water sample, and can not carry out enrichment and absorption to it.
In addition, if at the scene sampling, the used device in laboratory is no longer applicable so, therefore need to improve water sample separation and concentration device for above-mentioned defective, accelerate its filter velocity, improve and filter and adsorption efficiency, and make it have the organic effect of enrichment, can also be applicable to on-the-spot water sample separation and concentration.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of filter velocity fast, sample is had inrichment, and be suitable for the persistent organism water sample with bulk mass separation and concentration device of on-the-spot sample separation enrichment.
Persistent organism water sample with bulk mass separation and concentration device of the present invention is realized by following technical proposals:
A kind of persistent organism water sample with bulk mass separation and concentration device, comprise liquid storage bottle and with liquid storage bottle by the filtrator that clip is flexibly connected, the top cover with water inlet is arranged above liquid storage bottle, this water inlet is connected with sample feeding pipe; Above device also comprises the receiving bottle that is connected by rubber plug with filtrator, and rubber plug seals up receiving bottle, is connected with the safety flack of anti-suck between receiving bottle and the vacuum pump by flexible pipe, and the sample feeding pipe in the safety flack is lower than the position that goes out the sample pipe; The below bottle mouth position of liquid storage bottle has lock piston with holes, and whether this lock piston at any time Quality control solution is injected in the filtrator; Scale is arranged on the receiving bottle, can read at any time the volume of the sample that has filtered in the receiving bottle.
Filter I and filter II that filtrator comprises glass funnel and matches with it respectively and seal, the filter I matches with the upper roof of glass funnel; At the glass funnel madial wall annular boss is arranged, the filter II matches with annular boss.
Be connected with core in the intubate of glass funnel below, there is enriched layer the core top, enriched layer comprises the enrichment cylinder, its material of enrichment cylinder is transparent organic glass, this enrichment cylinder comprises barrel wall and the cover that matches and merge to be flexibly connected with barrel wall, a plurality of limberss are arranged on the cover, in the enrichment cylinder enrichment material is arranged, this resin make the dissolved organic matter in the fluid sample can enrichment and the particle that will contain organic suspended state can collect simultaneously, can study more easily the solid-liquid of organism in solution and distribute rule.
Above enrichment material can be any in XAD resin, activated charcoal or the isocyanurate foam.
Beneficial effect of the present invention is, has adopted said apparatus, can separate and enrichment sample in the sampling location; Owing to be provided with double-deck filter plate in the filtrator, in intubate, be provided with enriched layer, can not only the particulate separation of the suspended state of persistent organism will be contained, filter velocity and efficient have been improved, effectively enrichment solubilised state persistent organism can be studied more easily the level of pollution in the two-phase of persistent organism in environmental water sample and distribute rule simultaneously.
