Abstract
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
The present invention relates to a kind of chemical experiment device for magnetic composite particle suspension segregation program, belong to the analytical test field.
Background technology
In the analytical test experimental work, for the water analysis object, with micron order or nano level magnetic composite particle trapping agent absorption object, then separate with permanent magnet the magnetic composite particle trapping agent that has adsorbed object, adsorbed from this through elution program again the magnetic composite particle trapping agent of object and isolated object, for Instrumental Analysis sample introduction thereafter, this is the standby sample means of a kind of very efficient Instrumental Analysis among at present flourish.
