Background technology
Laboratory is in fluid sample during persistent organism enrichment, often can use microanalysis filtration unit, this device comprises liquid storage bottle, filtrator and receiving bottle, when in fluid sample, suspended particulate substance is more, filter membrane is easily caused to block, therefore filtrator needs frequently to change filter membrane, and experimenter has to the sample outwelled in liquid storage bottle, wastes sample greatly; The filter plate that filtrator above-mentioned in addition comprises glass funnel and matches with this funnel, during filtration, puts glass fiber filter on filter plate upper berth, and fluid sample, by membrane filtration, penetrates in funnel by filter plate, then enters in receiving vessel.Its defect of above filtrator is: sample solution very easily blocks filter membrane and filter plate when filtering, and 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In addition, if sample at the scene, the device that so laboratory is used is no longer applicable, therefore need to improve water sample separation and concentration device for above-mentioned defect, accelerate its filter velocity, improve and filter and adsorption efficiency, and make it have the organic effect of enrichment, on-the-spot water sample separation and concentration can also be applicable to.
Summary of the invention
For solving the problems of the technologies described above, the invention provides a kind of filter velocity fast, have inrichment to sample, and be suitable for the persistent organism water sample with bulk mass separation and concentration device of field sample separation and concentration.
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, the filtrator comprising liquid storage bottle and be flexibly connected by clip with liquid storage bottle, above liquid storage bottle, have the top cover of band water inlet, this water inlet is connected with sample feeding pipe; Above device also comprises the receiving bottle be connected by rubber plug with filtrator, and receiving bottle seals up by rubber plug, 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 going out sample pipe; The below bottle mouth position of liquid storage bottle has lock piston with holes, and whether this lock piston can be injected in filtrator by Quality control solution at any time; Receiving bottle there is scale, the volume of the sample filtered in receiving bottle can be read at any time.
Filtrator comprises glass funnel and matches with it respectively and the filter I sealed and filter II, and filter I matches with the upper roof of glass funnel; Have annular boss at glass funnel madial wall, filter II matches with annular boss.
Core is connected with in intubate below glass funnel, enriched layer is had above core, enriched layer comprises enrichment cylinder, its material of enrichment cylinder is transparent organic glass, this enrichment cylinder comprises barrel wall and to match the cover merging and be flexibly connected with barrel wall, cover there is multiple limbers, enrichment material is had in enrichment cylinder, this resin enables the dissolved organic matter enrichment in fluid sample and can be collected by the particle containing organic suspended state simultaneously, can study organism solid-liquid Distribution dynamics in the solution more easily.
Above enrichment material can be any one in XAD resin, activated charcoal or isocyanurate foam.
Beneficial effect of the present invention is, have employed said apparatus, can be separated and enrichment in sampling location to sample; Owing to being provided with double-deck filter plate in filtrator, enriched layer is provided with in intubate, can not only by the particulate separation of the suspended state containing persistent organism, improve filter velocity and efficiency, can also the simultaneously persistent organism of enrichment solubilised state effectively, the level of pollution in the two-phase of persistent organism in environmental water sample and Distribution dynamics can be studied more easily.
