Abstract
The utility model discloses a take filtering capability's solid-phase extraction post belongs to the chemical analysis laboratory and uses processing apparatus before the sample. The solid phase extraction column comprises a column tube, a filter screen, a filter head, a sample bin, an adapter and a transmission tube. The filter head is located the column casing top and links to each other with the column casing, and the sample storehouse is located the filter head top, is equipped with the adapter on the sample storehouse, and the sample storehouse passes through the adapter and links to each other with the filter head. The filter head is provided with a filter screen which is positioned in the column tube. The column tube is provided with a transmission tube, the filter head can be taken down from the column tube, and the sample bin can be taken down from the filter head. The beneficial effects of the utility model are that, simple structure, convenient to use can realize filtering sample solution before the solid phase extraction to can once only shift sample solution, reduced the human cost, improved experimental efficiency.
Description
Technical Field
The utility model relates to a chemistry analysis laboratory is with sample pretreatment device, especially a take filtering capability's solid phase extraction post.
Background
The solid phase extraction technology can realize that a liquid sample solution passes through an adsorbent to retain a detected substance, then a solvent with proper strength is selected to flush out impurities, and then a small amount of solvent is used for rapidly eluting the detected substance, thereby achieving the purposes of rapid separation, purification and concentration. Because the sample entering the solid phase extraction column contains the sample matrix, if the solid phase extraction is directly carried out, the extraction column is blocked, the operation is slow if the extraction column is light, the experimental efficiency is influenced, and the sample solution cannot be extracted if the extraction column is heavy, so the experiment fails. In addition, the capacity of the solid phase extraction column is limited, and if more sample solution needs to be extracted, the sample solution needs to be added in a plurality of times and is watched by a specially-assigned person, so that the working efficiency of a laboratory is influenced.
Disclosure of Invention
The above-mentioned not enough to laboratory solid phase extraction process exists, the utility model provides a take filtering capability's solid phase extraction post.
The utility model provides a technical scheme that its technical problem adopted is: a solid phase extraction column with a filtering function comprises a column tube, a filter screen, a filter head, a sample bin, an adapter and a transmission tube. The filter head is located the column casing top and links to each other with the column casing, and the sample storehouse is located the filter head top, is equipped with the adapter on the sample storehouse, and the sample storehouse passes through the adapter and links to each other with the filter head.
The filter head is provided with a filter screen which is positioned in the column tube.
The column tube is provided with a transmission tube for the outflow of the activating reagent, the sample solution, the leacheate and the eluent.
The filter head can be taken down from the column tube, and the sample bin can be taken down from the filter head, so that the filter head can be repeatedly used after being cleaned, and the cross contamination of samples can be prevented.
The beneficial effects of the utility model are that, simple structure, convenient to use can realize filtering sample solution before the solid phase extraction to can once only shift sample solution, reduced the human cost, improved experimental efficiency.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
Detailed Description
As shown in fig. 1, a solid phase extraction column with a filtering function comprises a column tube 1, a filter screen 2, a filter head 3, a sample chamber 4, an adapter 5, and a transmission tube 6. The filter head 3 is located the column casing 1 top and links to each other with column casing 1, and sample storehouse 4 is located filter head 3 top, is equipped with adapter 5 on the sample storehouse 4, and sample storehouse 4 passes through adapter 5 and links to each other with filter head 3.
The filter head 3 is provided with a filter screen 2, and the filter screen 2 is positioned in the column tube 1.
The column tube 1 is provided with a transmission tube 6 for flowing out of the activating reagent, the sample solution, the leacheate and the eluent.
The filter head 3 can be taken down from the column tube 1, and the sample chamber 4 can be taken down from the filter head 3, so that the filter head can be repeatedly used after being cleaned, and the cross contamination of samples can be prevented.
The embodiment described is only an embodiment of the present invention, and all other embodiments obtained by a person skilled in the art without creative work are all included in the protection scope of the present invention.
