Description
Technical Field
The utility model relates to the field of chemical analysis experiments, in particular to an MOFs purification column.
Background
Laboratory samples usually need to be purified to remove impurities before entering an instrument for analysis and detection, matrix interference is eliminated, and the purification materials used in the existing purification mode are single, limited in adsorption capacity and incapable of being reused. The MOFs material has the characteristics of large specific surface area, good thermal stability, adjustable pore size, uniform pore size distribution, adjustable surface modification capacity and the like, the functionalized MOFs material is used as a purification material for pretreatment of various drug residues, and after adsorption and elution of a target compound, adsorption and separation of a trace target compound can be realized, so that the detection requirement of a low detection limit compound can be met. At present, no purification column special for MOFs materials exists in laboratory detection.
Disclosure of Invention
In order to solve the technical problems, the utility model is realized by the following technical scheme:
the utility model provides an MOFs purification column, and aims to solve the problems that the existing purification column is single in purification material, limited in adsorption capacity and incapable of being reused.
The technical scheme adopted by the utility model for solving the technical problems is as follows: the utility model provides a MOFs purifies post, includes column pipe, connector, purification chamber, filter, purifies the chamber and is located the column pipe below, purifies the chamber and passes through the connector and link to each other with the column pipe, and the filter is fixed in and purifies the chamber below, purifies intracavity portion and is equipped with MOFs purifying material, and the bottom is equipped with the filtration sieve, prevents that MOFs purifying material from getting into the filter.
The column tube is provided with scales which can display the volume of the solution.
The upper end of the purification cavity is provided with a sealing cover, and MOFs purification materials can be replaced by opening the sealing cover.
When the purification operation is carried out, the sample solution to be purified is added into the column tube, and the solution directly enters the receiving bottle for measurement through the purification cavity and the filter in sequence.
In order to accelerate the purification speed, the flow of the sample solution to be purified can be accelerated by adopting a positive pressure or negative pressure mode.
The utility model has the advantages that the large adsorption capacity of the MOFs material is utilized to realize the rapid purification of the target object, and meanwhile, the filtration of the purified solution is completed, so that the pretreatment and purification speed of the sample can be accelerated, and the analysis and detection efficiency is improved.
Drawings
Fig. 1 is a schematic structural view of the present invention.
Detailed Description
As shown in figure 1, an MOFs purifies post, including column pipe 1, connector 2, purification chamber 3, filter 4, purification chamber 3 is located column pipe 1 below, and purification chamber 3 passes through connector 2 and links to each other with column pipe 1, and filter 4 is fixed in and purifies chamber 3 below, purifies the inside MOFs purifying material that is equipped with in chamber 3, and the bottom is equipped with filtering screen 7, prevents that MOFs purifying material from getting into filter 4.
The column tube 1 is provided with a scale 5 which can display the volume of the solution.
The upper end of the purification cavity 3 is provided with a sealing cover 6, and MOFs purification materials can be replaced by opening the sealing cover 6.
When the purification operation is carried out, a sample solution to be purified is added into the column tube 1, and the solution directly enters the receiving bottle for measurement through the purification cavity 3 and the filter 4 in sequence.
In order to accelerate the purification speed, the flow of the sample solution to be purified can be accelerated by adopting a positive pressure or negative pressure mode.
The described embodiment is only one embodiment of the present invention in order to better explain the principles of the utility model and the practical application, thereby enabling others skilled in the art to better understand and utilize the utility model. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.
