Abstract
The utility model provides a multi-channel solid phase extraction glass column which comprises a substrate made of tempered glass and is characterized in that a plurality of rectilinear extraction pipelines that are parallel to one another are arranged in the middle of the substrate; outlets communicated with the exterior of the substrate are formed at the two ends of each extraction pipeline; and extraction fillers are arranged in the extraction pipelines. The multi-channel solid phase extraction glass column has the beneficial effects that as the tempered glass acts as the substrate, the multi-channel solid phase extraction glass column has the advantages of attractive appearance, corrosion prevention, stable structure, transparence, no plasticizing agent, easiness in processing, and the like; in addition, with the adoption of the eight-channel extraction pipelines, multiple samples can be processed simultaneously, and the operating efficiency is high.
Description
Technical field
The utility model relates to a kind of chemical plant installations, especially solid-phase extraction device.
Background technology
In the safety detection field of food, environment and medicine, the pre-treatment of sample is a crucial step, and the pre-treatment quality of sample not only influences the final analysis result, service life that also can the impact analysis instrument.Therefore, chemist constantly improves the method for sample pre-treatments, makes it simpler, quick, accurate, efficient.Solid phase extraction techniques is to be combined and a sample pre-treatments technology developing out by liquid-solid extraction and liquid chromatogram, the mode that adopts selective absorption, selective elution to sample separate, purification and enrichment.It is simple, quick, has simplified the step of sample pre-treatments, has shortened the processing time; Selectivity is strong; Reduced the consumption of solvent, reduced pollution and cost, developed into a kind of strong tool of separating and concentrating trace analysis material in the various samples environment.SPE is applied to the pre-treatment of various complex matrices more and more widely, has become the mainstream technology of analyzing pre-treatment at present.
Solid-phase extraction column is divided into post material and filler usually.Column material often is made up of the polypropylene for medical article column jecket, and there is the porous filter disc at two ends, interior charge.In the face of serious day by day plasticiser disturbance, solid phase extraction techniques can be used more and more wider, but as the solid-phase extraction column of sample detection, itself also probably contains plasticiser, thereby influences the accuracy and the reliability of final detection result.Therefore, need a kind of column material more reliably to solve this problem.Glass does not exist the possibility of adding plasticiser in its production technology; Therefore can obtain the actual content of sample more accurately, objectively; Glass will be used as the solid-phase extraction column of column material in increasing acquisition; Multichannel SPE glass column will be used widely, thereby realizes reliable, quick and easy.
The utility model content
The utility model provides a kind of solution of the above problems, and a kind of simple in structure, a kind of multichannel SPE glass column of not containing plasticiser is provided.
The technical scheme of the utility model provides a kind of multichannel SPE glass column; It comprises the substrate of being processed by tempered glass; It is characterized in that: be provided with several linear that is parallel to each other extraction pipelines in the middle of the said substrate; The two ends of said extraction pipeline are provided with and are communicated to the outside outlet of said substrate, are provided with extraction stuffing in the said extraction pipeline.
Preferably, said extraction stuffing is carbon 18 or silica gel.
Preferably, said substrate is provided with eight said extraction pipelines.
Preferably, it comprises the two said substrates that are stacked together that are parallel to each other, and the phase of said substrate is provided with half groove of forming said extraction pipeline to the inside.Two said substrates pass through polishing mutually to the inside, make that sealing closely each other.
The beneficial effect of a kind of multichannel SPE glass column of the utility model is: use tempered glass as substrate, have attractive in appearance, corrosion-resistant, Stability Analysis of Structures, be easy to processing, and transparent, do not contain advantage such as plasticiser; In addition, adopt the extraction pipeline of eight passages, can handle a plurality of samples simultaneously, operating efficiency is high.

Fig. 2 is the side view of a kind of multichannel SPE glass column of the utility model;
Fig. 3 is the cutaway view of substrate 10.
The specific embodiment
The specific embodiment in the face of the utility model is described in further detail down.
As shown in Figure 1, a kind of multichannel SPE glass column of the utility model comprises the substrate of being processed by tempered glass 10.Be provided with 8 linear extraction pipelines 12 that are parallel to each other in the middle of the substrate 10.The two ends of extraction pipeline 12 are provided with the outlet 14 that is communicated to substrate 10 outsides.Be provided with extraction stuffing 16 in the extraction pipeline 12, extraction stuffing 16 is carbon 18 or silica gel.
As shown in Figures 2 and 3, a kind of multichannel SPE glass column of the utility model comprises that two are parallel to each other, and the substrate 10 that is stacked together.The phase of substrate 10 is provided with half groove 18 to the inside, and after two substrates 10 was stacked together, half groove 18 on the two substrates 10 was formed complete extraction pipeline 12.Two substrates 10 passes through polishing mutually to the inside, makes that sealing closely each other.
A kind of multichannel SPE glass column of the utility model in use; Connect one of extraction pipeline 12 through flexible pipe earlier and bring out mouth 14; Solution to be extracted is injected in the extraction pipeline 12; Through the filtration of extraction stuffing 16, discharge from other end outlet 14 successively after the composition in the solution is separated, thereby realize extraction.During use, can use simultaneously by eight extraction pipelines 12, thereby improved operating efficiency.Because substrate 10 adopts transparent tempered glass, not only Stability Analysis of Structures, be easy to processing, and stopped to mix the extraction process possibility of plasticiser from the source; Whole operation process in addition; Can estimate, thereby can control whole process, good operability at any time.
Above embodiment is merely the utility model a kind of embodiment wherein, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model claim.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to the protection domain of the utility model.Therefore, the protection domain of the utility model patent should be as the criterion with accompanying claims.
