In addition, if sampling at the scene, laboratory device used is no longer applicable so, therefore need to improve water sample separation and concentration device for above-mentioned defective, accelerate its filter velocity, improve and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 utility model provide 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 utility model is realized by following technical proposals:
A kind of persistent organism water sample with bulk mass separation and concentration device comprises liquid storage bottle and the filtrator that is flexibly connected by clip with liquid storage bottle, and the top cover with water inlet is arranged above liquid storage bottle, and 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 vacuum pump by flexible pipe, and the sample feeding pipe in 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 Quality control solution at any time is injected in filtrator; Scale is arranged on receiving bottle, can read at any time the volume of the sample that has filtered in 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 cover, in the enrichment cylinder, enrichment material is arranged, this resin make the dissolved organic matter in 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 isocyanurate foam.
The beneficial effects of the utility model are, have adopted said apparatus, can separate and enrichment sample in the sampling location; Owing to being provided with double-deck filter plate in filtrator, be provided with enriched layer in intubate, can not only the particulate separation of the suspended state of persistent organism will be contained, filter velocity and efficient have been improved, the persistent organism of enrichment solubilised state effectively, can study more easily the level of pollution in the two-phase of persistent organism in environmental water sample and distribute rule simultaneously.
