Abstract
The utility model relates to a novel solid-phase extraction column, and belongs to the technical field of the extraction. The outer diameter of the upper part of a connection cover is greater than that of the lower part, a mounting table is arranged between the upper part and the lower part of the connection cover, the mounting table is in threaded connection with the upper part of a pipe jacket A in a matching manner, the pipe jacket A is in threaded connection with a tubular column B in the matching manner, the tubular column B is in threaded connection with a tubular column C in the matching manner, and a water outlet is formed in the lower part of the tubular column C; a lower sieve plate, fillers and an upper sieve plate are sequentially arranged inside the pipe jacket A, the tubular column B and the tubular column C from bottom to top.
Description
Technical field
The utility model relates to a kind of novel solid-phase extraction column, belongs to the abstraction technique field.
Background technology
It is increasingly sophisticated that modern separate analytical technique is faced with analytic target, and the content of the relevant composition of analyte is more and more lower, and for this reason, the The pretreatment technology is outstanding in sample analysis to show important.The matrix solid phase extraction techniques is the sample pretreatment technology that is based upon a kind of Separation of Solid and Liquid extraction on the solid phase extraction techniques basis, directly with the testing sample through mixing and grinding and adsorbent etc. as the matrix extraction column of packing into, take off to wash and concentrate with solvent and finish The pretreatment.General solid-phase extraction column, have for disposable product, with after namely abandon, cause waste, big with post quantity for the extraction of batch samples, extract the cost height; But though and laboratory used nature of glass solid-phase extraction column repeated application, length is fixed, the post internal volume is less, the dress post tamps difficulty, and is difficult to all samples is carried out extracting and enriching, versatility is poor.
Summary of the invention
The utility model is at the proposition of above problem, and develops a kind of novel solid-phase extraction column.
The top external diameter of access flap of the present utility model is greater than lower outer diameter, locate to arrange erecting bed between the top of access flap and the bottom, erecting bed is connected with the top threaded engagement of column jecket one, column jecket one is connected with tubing string two threaded engagement, tubing string two is connected with tubing string three threaded engagement, and the bottom of tubing string three sets out the mouth of a river; Column jecket one, tubing string two sets gradually down sieve plate, filler and upper sieve plate with the inside of tubing string three from the bottom to top.
Access flap, column jecket one, tubing string three and tubing string two are made by material.
The utility model principle and beneficial effect: the utility model can lengthen extraction column as required, can be a plurality of tubing string two continued accesses.Improve versatility and convenience like this.
Owing to adopted technique scheme, the utility model not only is convenient to produce because it is simple in structure, and cost is very cheap is suitable for extensive popularization.
Description of drawings
Fig. 1 is profile of the present utility model.
Among the figure: 1. access flap, 2. erecting bed, 4. column jecket one, 5, upper sieve plate, 6, filler, 7, sieve plate, 10. tubing string two, 11. tubing strings three down.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is described further:
A kind of novel solid-phase extraction column; The top external diameter of access flap 1 is greater than lower outer diameter, locate to arrange erecting bed 2 between the top of access flap 1 and the bottom, erecting bed 2 is connected with the top threaded engagement of column jecket 1, column jecket 1 is connected with tubing string 2 10 threaded engagement, tubing string 2 10 is connected with tubing string 3 11 threaded engagement, and the bottom of tubing string 3 11 sets out the mouth of a river; Column jecket 1, tubing string 2 10 sets gradually down sieve plate 7, filler 6 and upper sieve plate 5 with the inside of tubing string 3 11 from the bottom to top.
Access flap 1, column jecket 1, tubing string 3 11 and tubing string 2 10 are made by polypropylene material.
The above; it only is the preferable specific embodiment of the utility model; but protection domain of the present utility model is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the utility model discloses; be equal to replacement or change according to the technical solution of the utility model and inventive concept thereof, all should be encompassed within the protection domain of the present utility model.
