Description
Technical field
This utility model belongs to laboratory paraphernalia, relates to a kind of large volume liquid Solid-Phase Extraction device for storing liquid.
Background technology
Solid-Phase Extraction (SPE) is the conventional sample pretreatment mode that laboratory chemical is analyzed, and is widely used in food, guarantor
In the analyzing detecting method in the fields such as strong product.In conventional method of analysis, sample add certain volume solvent extraction, by from
The mode such as the heart, filtration obtains supernatant, and by all or point take part supernatant and concentrate by Solid-Phase Extraction column purification, food inspection
In survey method, the volume of this supernatant usual is typically small, often at below 20ml, although flow rate of liquid is relatively slow during Solid-Phase Extraction, but
Less loading volume still can be carried out in the way of manually supplementing sample, and the whole process time can also control
Within an hour.
Along with rising year by year of Environmental Protection in China consciousness, supervision department and society are for the weight of pollutant in environment water
Visual range subsist benefit improve.At present, all kinds of pollutant levels in environment water have become the important indicator of environmental evaluation, and list in
The daily monitoring system of China's most of area surroundings supervision.Therefore, different pollutant accurate qualitative fixed in environment water
Amount becomes the focus of attention of chemical analysis field, delivering of pertinent literature and promulgating as actual analysis detection of environmental standard
Provide sufficient theoretical foundation.But, take a broad view of relevant criterion and the analysis detection of pollutant in water body that documents and materials relate to
Method, in addition to the mode of part employing liquid-liquid extraction carries out pre-treatment, great majority all use the solid phases extraction of large volume liquid loadings
Follow the example of.The most also there are many full automatic environmental water sample automatic solid-phase extractors, but expensive, and small-sized environment measuring is real
Test the less of room outfit.
When following standard method and carrying out actual sample process, the pendulum maximum problem in face of experimenter is substantially
Hydrops body Solid-Phase Extraction will take a substantial amount of time, and be affected by factors such as Solid-Phase Extraction column capacity, flow velocitys, and this process is compared
Increasingly complex in routine operation.When particularly Multi-example processes, usually there will be because operation does not slowly catch up with the liquid rate of outflow
The loading stage solid phase extraction column stuffing caused dries up, and causes on sample liquid the feelings such as wrong solid-phase extraction column because of maloperation or sample mix
Condition, the serious accuracy affecting experimental data.
At present, common are two kinds of solid-phase extraction devices being applied to large volume liquid on the market.One is tool sealing column
The catheter of head, links with solid-phase extraction column, and the other end inserts sample bottle, vacuum pump and pressure valve coutroi velocity.But this kind of dress
The shortcoming put is that sample bottle bottleneck opens wide, and dust or other granules in indoor environment may fall in sample bottle and cause dirt
Dye.Meanwhile, sample cannot be completely drawn out by this device, and residual sample still needs to manual loading, and in use pipeline imbibition
Mouth may expose to cause loading stage solid phase extraction column stuffing to dry up in air, still needs to laboratory technician's whole process prison in use
See operation.Another kind is to use special wide-mouth solid-phase extraction column, buckles sample bottle above.But this kind of mode can be at back-off sample
Occur during product bottle that liquid sprays or overflows from junction, coutroi velocity need to be coordinated to operate, need higher skilled operation degree.With
Time, purchase special solid-phase extraction column relatively costly, testing cost rises.
Therefore laboratory urgently one can complete whole sample liquid loading process under without laboratory technician's policing operation at present, behaviour
Make simple and convenient and without purchasing the large volume liquid solid phase extraction method of special solid-phase extraction column.
Summary of the invention
This utility model can provide a kind of large volume liquid Solid-Phase Extraction device for storing liquid, can be in the feelings of no supervision operation
Whole sample liquid loading process is completed under condition, and simple and convenient, with low cost.
For realizing above-mentioned functions, the sample bottle that this utility model relates to seals lid and is characterised by, including tool lid reservoir
With liquid guide pipeline two parts, material is polypropylene or glass, and material selects according to the analyte of detection, can meet below 2L
The Solid-Phase Extraction of fluid sample uses demand.
Tool lid reservoir includes dust cap 2, liquid storage pipe 3 and detachable end pipe 5, and dust cap 2 is by clip or in the way of screwing
Link with liquid storage pipe 3 upper end, to ensure isolation sample liquid and experimental situation, to avoid ash fall and the sealing of liquid storage pipe 3.Dust cap
2 centers tool round platform hollow catheter entrances 1 wide at the top and narrow at the bottom, with dust plug 7 with the use of, play adjustment intraductal atmospheric pressure and secondary
Dust-proof function, virtual pressure is in catheter entrance 1 in use, balances pressure in liquid storage pipe 3 while preventing ash fall, it is to avoid
The phenomenon that drawing liquid is the most smooth occurs.Liquid storage pipe 3 lower end pinching is hollow circuit cylinder, and has toroidal membrane 4, annular at hollow-cylindrical interior
Dividing plate 4 and fixing plug 8 with the use of, catheter 9 liquid sucting port can be fixed bottom pipe of the detachable end 5, it is ensured that completely taking out of liquid
Take loading.Detachable end pipe 5 is nested with hollow circuit cylinder and links and be detachable structure, sealing ring fixing seal.
Liquid guide pipeline includes sealing stigma 6, dust plug 7, catheter 9 and fixing plug 8, and seals stigma 6, dust plug 7 and
Fixing plug 8 is round table-like and is placed on catheter 9, and dust plug 7 size is consistent with catheter entrance 1, and fixing plug 8 upper table surfaces are straight
Footpath size between hollow circuit cylinder interior diameter and toroidal membrane 4 annular diameters, seal the specification of stigma 6 and the length of catheter 9,
Depending on shape is because of actually used demand.If glass material, being typically set to U-shaped by catheter 9, one end is longer stretches into tool lid storage
Liquid device, the other end links with solid-phase extraction column.If polypropylene material, then catheter 9 is long soft-pipe, and tool lid liquid storage is stretched in one end
Device, the other end links with solid-phase extraction column.
Beneficial effect: this utility model relates to a kind of large volume liquid Solid-Phase Extraction device for storing liquid.Dust cap 2, empty drain
Tube inlet 1 and dust plug 7 with the use of, can be dust-proof and adjust intraductal atmospheric pressure and avoid the most smooth phenomenon of drawing liquid, it is ensured that sample liquid cleans
It is drawn loading smoothly.Toroidal membrane 4 and fixing plug 8 with the use of, catheter 9 liquid sucting port can be fixed in pipe of the detachable end 5
Bottom, it is ensured that the integrity of loading.Detachable end pipe 5 is nested with hollow circuit cylinder and link and for detachable structure, if testing needs,
Pipe of the detachable end 5 can be dismantled, the very small amount liquid transfer loading that will wherein remain.Pass through sealing ring, it is ensured that sealing.Poly-
Propylene and two kinds of selections of glass material, can fully meet different detection demand.
Use of the present utility model can complete whole sample liquid loading process, and operation letter in the case of no supervision operates
Single convenient, with low cost, it is possible to meet the analysis to liquid (such as water sample or organic extract) sample and detect demand.
