Abstract
The utility model belongs to the field of experimental devices, and in particular relates to a microanalysis filter. The microanalysis filter comprises a glass hopper and a filter plate matched and sealed with the glass hopper. The microanalysis filter is characterized in that a sand core is clamped in an inserting tube below the glass hopper; an enrichment layer is arranged above the sand core and comprises an enrichment cylinder; the enrichment cylinder comprises a cylinder body and a cylinder cover matched and movably connected with the cylinder body; a limber hole is formed in the cylinder cover; and an enrichment material is put in the enrichment cylinder. The microanalysis filter has the beneficial effects that with the adoption of the microanalysis filter with the above structure, dissolved organics in a liquid sample can be enriched and suspended particles containing the organics can be simultaneously collected because of arrangement of the enrichment layer in the inserting tube of the filter, so that the solid-liquid distribution rule of the organics in a solution can be conveniently researched.
Description
Technical field
The utility model belongs to the experimental provision field, is specifically related to a kind of micro-analysis filter.
Background technology
Practical chamber is when filtering fluid sample; often can use the micro-analysis filter; this filter comprises glass funnel and the filter plate that matches and be tightly connected with this funnel; during filtration; put glass fiber filter on the filter plate upper berth; fluid sample is penetrated in the funnel by filter plate by membrane filtration, then enters in the receiving vessel.Above its defective of filter is: this filter can not adsorb the organic matter of solubilised state, therefore need to improve for above-mentioned defective, make the dissolved organic matter in the fluid sample can enrichment and the particle that will contain organic suspended state collected filter simultaneously.
Summary of the invention
For solving the problems of the technologies described above, the utility model provides a kind of makes the dissolved organic matter in the fluid sample can enrichment and the particle that will contain organic suspended state collected micro-analysis filter simultaneously.
Micro-analysis filter of the present utility model, realize by following technical proposals:
A kind of micro-analysis filter, comprise glass funnel and the filter that matches with glass funnel, be connected with core in the intubate of glass funnel below, there is enriched layer the core top, enriched layer comprises the enrichment cylinder, this enrichment cylinder comprises barrel wall and the cover that matches and merge to be flexibly connected with barrel wall, and at least one limbers is arranged on the cover, in the enrichment cylinder enrichment material is arranged.
Above-mentioned enrichment material is any in XAD resin, active carbon or the polyurethane foam.
Above-mentioned its material of enrichment cylinder is transparent lucite.
The beneficial effects of the utility model are, adopted the micro-analysis filter of said structure, owing in the intubate of filter, being provided with enriched layer, make 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 organic matter in solution and distribute rule.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of enrichment cylinder of the present utility model;
Among the figure, 1-filter, 2-glass funnel, 3-limbers, 4-resin, 5-enrichment cylinder, 6-core, 7-cover, 8-intubate.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further described, so that those skilled in the art understand the utility model.
A kind of micro-analysis filter, comprise glass funnel 2 and the filter 1 that matches with glass funnel 2, be connected with core 6 in the intubate 8 of glass funnel 2 belows, there is enriched layer core 6 tops, enriched layer comprises enrichment cylinder 5, and enrichment cylinder 5 its materials are transparent lucite, and this enrichment cylinder 5 comprises barrel wall and the cover 7 that matches and merge to be flexibly connected with barrel wall, at least one limbers 3 is arranged on the cover 7, the XAD resin 4 of enrichment has been arranged in the enrichment cylinder 5.
When sample solution filters in by above filter, 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 organic matter in solution and distribute rule.
