Technical field
The utility model belongs to technical field of analysis and detection more particularly to a kind of aprepitant intermediate detection device.
Background technique
It is well known that liquid chromatograph mainly includes；Liquid storage bottle, high pressure pump, sample injector, chromatographic column, detector etc.
Several part-structures.Mobile phase in liquid storage bottle successively finally flows into waste liquid through high pressure pump, sample injector, chromatographic column, detector
Bottle.Since liquid chromatogram instrument pipeline and chromatographic column filler are generally micron order, so the minute solid particles pole in mobile phase
Entire instrument system blockage phenomenon is easily caused, experimentation is influenced and even damages instrument, therefore the purity of mobile phase is wanted
It asks very high, usually requires that as chromatography pure reagent.It is small in mobile phase in order to further avoid when higher to requirement of experiment
Influence of the granule foreign to instrument and experiment, it is necessary to increase pot strainer device before chromatographic column.
And there is the disadvantages of filtering is slow, and filter effect is unobvious in the existing device for chromatograph filtering, when in use,
Since filtering filtration on paper there are residual particles, filter paper is caused to block, therefore filter slowly, popularity rate is lower in practical applications.
Utility model content
The utility model provides a kind of for detecting aprepitant intermediate to solve shortcoming in the prior art
Detection device.
In order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of aprepitant intermediate detection device, including the filter between sample injector and liquid-phase chromatographic column,
Filter includes filter cavity and filter core, and filter cavity includes successively affixed filter housing end cap, filter housing and inner connecting end；Filter housing end
It covers and is equipped with inlet；Filter core includes the filter element shell in filter housing and the end cover of filter element set on filter element shell end, filter core
The first filtering layer, the second filtering layer and third filtering layer are successively arranged in shell；End cover of filter element outer be equipped with it is parallel with filter element shell outside
Connecting pin, outer connecting pin are flexibly connected with inner connecting end；End cover of filter element is equipped with liquid outlet.
Further, outer connecting pin inner wall is connect with inner connecting end outer wall thread, and inner connecting end be located at outer connecting pin with
Between filter element shell.
Further, the first filtering layer, the second filtering layer and third filtering layer are spherical cap structure.
Further, the outer of the first filtering layer, the second filtering layer and third filtering layer is equipped with the support frame that cross section is annulus,
The outer wall of any support frame is set on filter element shell inner wall.
Further, support frame is set in a pair of of fixed link, and the end of fixed link is equipped with fixed block；Fixed block is set to
Outside filter element shell.
Further, the first filtering layer is located in the liquid inlet between the second filtering layer；First filtering layer is strainer, and the second filtering layer is machine
It is filter membrane, third filtering layer is water system filter membrane.
Further, filter housing end cap, filter housing and inner connecting end form filter chamber, inlet and liquid outlet be connected to filter chamber and
Extend to outside filter chamber.
Further, the observation panel being axially arranged along filter housing is offered on the filter housing of cylindrical structure.
By adopting the above technical scheme, the utility model has the advantages that
The utility model is flowed into filter chamber by inlet, and then in turn through three layers of filtering layer, fine particulate filter is fallen,
To make fine particle without being adhered on three layers of filtering layer, increase the filter effect of filter；The filter applicability is wider, and
And facilitate the replacement of filtering layer.
