Abstract
The invention relates to a magnetic composite micro-particle suspension segregation device applicable to a chemical laboratory, and belongs to the fields of analysis and testing. The invention aims to solve the problem that a conventional and ordinary segregation device for analyzing a magnetic composite micro-particle suspension in a chemical laboratory is too simple, so that the convenience in relevant segregation operation is affected. According to the device, two magic tapes which are mutually adhered and easy to be attached are used for restraining and positioning a permanent magnet together with a protecting shell of the permanent magnet on an outer surface of a side wall of a nonmagnetic container; the outline of the adhesion state of the magic tapes is similar to a wristwatch or a boxing champion gold belt, so that in the whole operation process that a trapping agent is segregated by using a magnetic field, action with higher tensity, for example, relevant analysis experiment operation personnel hold, press and position the slippery permanent magnet by hand, is avoided; by utilizing the device provided by the invention, relevant analysis experiment personnel can carry out the magnetic composite micro-particle suspension segregation operation in a relatively relaxed manner; and the device can also be used in small quantity preparation process of a magnetic composite micro-particle material self.
Description
technical field [0001] The invention relates to a magnetic composite microparticle suspension separation device suitable for chemical laboratories, which belongs to the field of analysis and testing. Background technique [0002] In the analysis and test experiment, for the water body analysis object, the target is adsorbed by the magnetic composite particle trap of micron or nanometer scale, and then the magnetic composite particle trap that has adsorbed the target is separated by a permanent magnet, and then eluted The program separates the target substance from the magnetic composite particle trap adsorbed on the target substance for subsequent instrumental analysis sample injection. This is a very efficient means of instrumental analysis sample preparation under vigorous development at present. [0003] The sample preparation means can also be expressed as a pretreatment means. [0004] The instrumental analysis sample preparation method for the purpose of analysis and ...
