Abstract
The utility model discloses belong to an organic system dehydration filter in the technical filed of dehydration and filtering, which is applied to the preparation of samples for analysis and testing. The organic system dehydration filter has a structure of an injector with a stopper; a filter membrane, a silica gel plate, anhydrous Na2SO4 and another silica gel plate are filled inside the organic system dehydration filter in sequence; and sizes of the silica gel plate and the filter membrane are in accord with the inner diameter of the injector. The dried anhydrous Na2SO4 is filled in the injector with the stopper, moisture in the samples can be effectively absorbed, the Na2SO4 is fixed through the silica gel plate and the filter membrane is added, dehydration and filtering can be further realized, the usage amount of the anhydrous Na2SO4 can be effectively reduced during the process of experimental dehydration while the operating efficiency is improved, and the production cost is greatly saved and environmental pollution level is reduced. The dehydration filter has good dehydration effect, can reduce the quantity of operation processes, and is environmentally friendly.
Description
Technical field
The utility model belongs to dehydration, filtration art, and particularly a kind of organic system dehydrator filter is applied to the preparation of test sample.
Background technology
Membrane filter is mainly used in the filtration of moving phase and sample in the stratographic analysis, does not have a good effect to protection chromatographic column and infusion pump guard system and sampling valve etc. are contaminated.It is widely used in gravimetric analysis, microanalysis, colloid separation and the sterility test, is the necessary pre-treatment articles for use of instrument sample introduction.Membrane filter is divided into two types of water system and various organic solvents usually, and the aperture can be 0.45,0.22,0.80um etc.If instrument selection gas chromatograph or GC-MS, the pre-treatment of sample just need to increase the process of dehydration, a large amount of anhydrous Na is often added in the laboratory
2SO
4As carrying out processed in the organic solution of dewatering agent behind the constant volume; Cause the sample detection more complicated and loaded down with trivial details; Therefore, people constantly try to explore various abbreviation step method, in the hope of the experimental article that obtains to improve detection efficiency, improves accuracy in detection.
The laboratory is divided into the completion of two steps mostly for dehydration, filtration at present, does not comprise that wherein syringe connects filtering head, sample adds anhydrous Na
2SO
4And anhydrous Na
2SO
4The process of oven dry, and because anhydrous Na
2SO
4Can continue from air, to absorb water in the put procedure of oven dry back, cause dehydrating effect to be difficult to guarantee, have a strong impact on instrument detecting result's accuracy.And in dehydration, often with a large amount of anhydrous Na
2SO
4Add in the organic solution and draw the moisture in the mother liquor, this has not only increased the detection cost, has influenced final testing result, but also has caused environmental hazard.
Summary of the invention
The utility model has overcome traditional anhydrous Na
2SO
4Dehydrating effect is unstable, the loaded down with trivial details shortcoming of operating process, in conjunction with the characteristics of filtering with microporous membrane, has designed a kind of organic system dehydrator filter with double medium filtration structure of dehydration layer and miillpore filter, can be used as dehydrator filter in a kind of detection.
Shown in accompanying drawing, the organic system dehydrator filter of the utility model design is a tool plug syringe construction, and inside is filled filter membrane 4, silica gel plate 3, anhydrous Na successively
2SO
42, silica gel plate 1; The size of silica gel plate, filter membrane is consistent with the syringe internal diameter; The syringe internal diameter is 10-30mm.
Described filter membrane 4 is the organic system filter membrane, and hole is 0.2-1.0 μ m.
Described anhydrous Na
2SO
42 dry by the fire 3-18h under 100-500 ℃, change in the exsiccator subsequent use after baking is good immediately.
Anhydrous Na
2SO
42 packed heights are 5-30mm.
The utlity model has following remarkable result:
Utilize the anhydrous Na of oven dry
2SO
4Be filled in the tool plug syringe, can effectively absorb the moisture in the sample, and through silica gel plate fix N a
2SO
4, add filter membrane, can a step realize dehydration, filter, when improving work efficiency, can effectively reduce anhydrous Na in the experiment dehydration
2SO
4Use, save production cost significantly and reduce environmental pollution.This dehydrator filter dehydrating effect is good, can reduce operating process and environmental friendliness.
