Description
Technical field
The utility model belongs to concentration determination instrument and equipment field, is specifically related to a kind of nucleopore membranes solution concentration detection instrument.
Background technology
Nucleopore membranes, has another name called nuclear track, etching-film, is the novel microporous filter membrane of one that development abroad is got up.This film utilizes the thermal neutron in nuclear reactor to make uranium---235 fissions, the fragment that fission produces penetrates organic high score plastic sheeting, and the path of fission fragment process stays a narrow irradiation damage passage.This passage, after oxidation, with suitable chemistry etches, can become the passage on film garden column micropore.Control radiation parameter and the etching condition of nuclear reactor, just can obtain the nucleopore membranes in different holes density and aperture.
The principal feature of nucleopore membranes has the identical straight micropore consistent with aperture of one or more shape penetrating film, the geometry of this rule makes its research very easily realize formulism and theorize, be therefore widely applied to that liquids and gases filter, blood cell is separated with cancer cell, the mensuration of particulate (activity of size, shape, charged particle), solution concentration mensuration, the field such as isotopic separation and Chemical Decomposition.
The nucleopore membranes solution concentration monitor (accompanying drawing 1) used in prior art, structure is simple, solution directly has inlet to enter, arrive nucleopore membranes, enter receiving flask through valve, use this kind of monitor of the prior art, there is following shortcoming: solution directly arrives nucleopore membranes, bring larger impact to nucleopore membranes, affect the serviceable life of nucleopore membranes; Need extra timing, cause error comparatively large like this, the accuracy that impact measures.
Utility model content
The purpose of this utility model is to provide the nucleopore membranes solution concentration detection instrument that a kind of structure is simple, accuracy of measurement is high.
