Description
Technical field:
The utility model relates to the filter technical field of sample analysis pre-treatment, is specifically related to disposable chromatogram sample introduction bottle-shape filter.
Background technology:
The research and development of disposable chromatogram sample introduction bottle-shape filter are a kind of innovations to chromatogram sample filtering mode.Traditional chromatographic sample filters will use the needle-based filter, fluid sample at first need be used the syringe sucking-off, connects the upper needle type filter then, and row pressure filtrate is waited for the automatic sampler sample introduction to the sample introduction bottle of chromatogram.This process need uses multiple consumptive material, needs on the step to shift sample twice, is difficult to avoid sample loss and change in concentration, especially for volume at the sample that biological sample and the solvent of micro updating is volatile reagent, produce bigger error.
The utility model content:
The purpose of this utility model provides a kind of disposable chromatogram sample introduction bottle-shape filter, and it is simple in structure, and easy operation also can reduce overall consumables cost when reducing time cost, and can obtain experimental result more accurately.
In order to solve the existing problem of background technology, the utility model is by the following technical solutions: it comprises dottle pin 1, aluminium lid 2, interior plug 3, filter membrane groove 4, filtration membrane 5, outer blank 6, the upper end that the upper end of described interior plug 3 arranges aluminium lid 2, aluminium lid 2 is provided with dottle pin 1, the bottom of interior plug 3 is provided with filter membrane groove 4, the inside of filter membrane groove 4 is provided with filtration membrane 5, plug 3 outsides in outer blank 6 is socketed in.
The internal diameter of described outer blank 6 is identical with the external diameter of interior plug 3.
Plug 3 high 18mm, internal diameter are that 6mm, external diameter are 8.5mm in described.
Described filtration membrane 5 external diameters are that 6mm, internal diameter are 4mm.
Described outer blank 6 whole height are 8.5mm for 24.5mm, internal diameter, and the bottleneck height is 4.5mm.
The utlity model has following beneficial effect: it is simple in structure, and easy operation also can reduce overall consumables cost when reducing time cost, and can obtain experimental result more accurately.
Description of drawings:
Fig. 1 is the utility model structure structural representation;
The specific embodiment:
Referring to Fig. 1, this specific embodiment is by the following technical solutions: it comprises dottle pin 1, aluminium lid 2, interior plug 3, filter membrane groove 4, filtration membrane 5, outer blank 6, the upper end that the upper end of described interior plug 3 arranges aluminium lid 2, aluminium lid 2 is provided with dottle pin 1, the bottom of interior plug 3 is provided with filter membrane groove 4, the inside of filter membrane groove 4 is provided with filtration membrane 5, plug 3 outsides in outer blank 6 is socketed in.
The internal diameter of described outer blank 6 is identical with the external diameter of interior plug 3.
Plug 3 high 18mm, internal diameter are that 6mm, external diameter are 8.5mm in described.
Described filtration membrane 5 external diameters are that 6mm, internal diameter are 4mm.
Described outer blank 6 whole height are 8.5mm for 24.5mm, internal diameter, and the bottleneck height is 4.5mm.
It is high density poly propylene that the material of described outer blank 6 and Nei Sai 3 is, the good tolerability that chemical reagent is had.The dimensional requirement of outer blank is consistent with 2mL chromatogram sample introduction bottle, can be placed directly on the array dish of automatic sampler, waits for sample introduction.
Described diaphragm material has polyether sulfone, nylon, polytetrafluoroethylene (PTFE), Kynoar etc., is fit to the filtration of various different chemical solvents.
This specific embodiment method of operating: when fluid sample adds outer blank, fill in the pressure to the outer blank bottom by pressing from top to bottom, force the fluid sample filter membrane, realize the separation of particle, in the plug, directly put into the chromatograph automatic sampler in the supernatant liquor that obtains directly is kept at, finish sample introduction.
This specific embodiment has following beneficial effect: it is simple in structure, and easy operation also can reduce overall consumables cost when reducing time cost, and can obtain experimental result more accurately.
