The invention relates to a device for a chemical experiment aiming at a magnetic composite particle turbid liquid separation procedure, belonging to the field of an analysis test. The scheme aims at solving the problems that the existing commonly-used device aiming at the separation of magnetic composite particle turbid liquid in an analytical chemistry laboratory is too simple so as to influence the convenience of relative separation operation. According to the scheme, two sticking belts which are in a mutual sticking state and are easy to detach are connected with a pocket-shaped permanent magnet packaging bag containing a flexible material of a permanent magnet left to right from two sides; the pocket-shaped permanent magnet packaging bag is bundled and positioned on the outer surface of the side wall of a non-magnetic container and an outline shape of the attached forms looks like a waist bag; therefore, in a whole operation process of separating a capturing agent by a magnetic field, one high-tension-degree movement of utilizing a hand to take and pinch, and press and position the smooth permanent magnet by a relative analytic experiment operator is avoided; and with the adoption of the device applying the scheme, the relative analytic experiment operator can relatively easily carry out relative magnetic composite particle turbid liquid separation operation.
Description
technical field [0001] The invention relates to a chemical experiment device for the separation procedure of magnetic composite microparticle suspension, 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 analysi...
