Description
Technical field
The described filtration of the utility model-SPE combined apparatus relates to a kind of teaching and the separating and filtering of production usefulness and the device of SPE coupling.
Background technology
SPE (SPE) is exactly the object that utilizes in the solid adsorbent adsorptive liquid sample, object is separated with interfering compound with the matrix of sample, and then attach with eluent wash-out or heating desorption, reaches the purpose of separation, purifying and enrichment object.Present existing native place extraction equipment all is that little water sample is handled, and for handling the high capacity water sample, directly carries out the SPE operation, is easy to stop up filler, and eluent comprised the content of target substance to be measured in the suspension simultaneously, influences the accuracy of water sample analysis.
To existing problem in the above-mentioned prior art, a kind of novel filtration of research and design-SPE combined apparatus can realize simultaneously that the separation of suspension in the water and the organism of dissolving part extract.
Summary of the invention
In view of existing problem in the above-mentioned prior art, the purpose of the utility model is a kind of novel filtration of research and design-SPE combined apparatus.In order to what exist in the solution prior art: 1, have only little water sample treatment facility, do not have big water sample solid-phase extraction device; 2, existing equipment is directly handled big water sample, the phenomenon of filler can occur stopping up; Existing equipment is directly handled big water sample, eluent can occur and comprise the content of target substance to be measured in the suspension simultaneously, influences the accuracy of water sample analysis.
The technical solution of the utility model is achieved in that
The described filtration of the utility model-SPE combined apparatus is made up of filtrator, glass-film container carrier, solid-phase extraction column and surge flask; Glass-film is equipped with in the inside that it is characterized in that described filtrator; The hollow steel needle of the bottom of filtrator is inserted among the container carrier I; Among the container carrier I solid-phase extraction column is housed, the bottom that the hollow steel needle of solid-phase extraction column bottom passes container carrier I is inserted among the container carrier II; Among the container carrier II surge flask is housed; Interface on container carrier I and the container carrier II is connected with gas control valve on the hyperchannel stainless steel pipe support through pipeline; On the hyperchannel stainless steel pipe support vacuum pump is housed.
On described container carrier I of the utility model and the container carrier II vacuum tightness micrometering valve is housed respectively.
Begin to operate the vacuum tightness micrometering valve on front opening vacuum pump and the container carrier I; The water sample of gathering is poured in the filtrator, opened the pneumatic vacuum valve that is connected with container carrier I simultaneously, and regulate the vacuum tightness micrometering valve on the container carrier I; Under action of pressure; Water sample is through glass-film, and suspended material is trapped the water sample after the filtration, imports the solid-phase extraction column in the container carrier I.When filtering solution imports solid-phase extraction column; Open pneumatic vacuum valve and the pneumatic control valve that is connected with container carrier II on the container carrier II simultaneously; Carry out the SPE process; Liquid for the control flow velocity, is regulated the vacuum tightness micrometering valve on container carrier I and the container carrier II through solid phase extraction column at any time.In the surge flask in the liquid inlet container carrier II after the extraction, extract, seal up for safekeeping with low amounts of water and prevent material volatilization to be analyzed to treating that water sample is accomplished.Before the end, the vacuum tightness micrometering valve be should open earlier, pneumatic vacuum valve and vacuum pump closed again.
The utility model has the advantages that conspicuously, mainly show:
The utility model comprises simultaneously and filters and 2 unit of SPE, through the adjustable channels valve, accomplishes synchronously and filters and the SPE process, realization separating and enrichment suspended material and dissolved substance in One's name is legion water sample, the high capacity water sample.
1, the utility model can directly be handled big water sample, the phenomenon of filler can not occur stopping up; Eluent can not occur and comprise the content of target substance to be measured in the suspension simultaneously, influence the situation of the accuracy of water sample analysis.
2, the utlity model has that short, sample size of running time and capacity greatly, do not need a large amount of extraction solvents, are suitable for analyzing volatility and nonvolatile matter, high repeatability and other advantages.
3, the utility model can be used for separation, enrichment and the analysis of complex target matter sample trace in the fields such as environmental chemistry, food, medical and health, clinical chemistry, biological chemistry, medical jurisprudence or trace.
4, the utility model is equipped with hyperchannel stainless steel pipe support, and every road is furnished with independently pneumatic vacuum valve and vacuum tightness micrometering valve, and it is flexible to handle sample size, and control is convenient, accurately controls flow velocity, and is durable in use.
The utlity model has novel structure, process advantages such as easy, easy to use, applied widely, safe and reliable, it puts goods on the market in enormous quantities and will produce positive social benefit and remarkable economic efficiency.
