Abstract
The invention relates to a chemical experiment device for isolating magnetic composite particle turbid liquid, and belongs to the field of analytical test. Aiming at the problem that as the generally used device for isolating magnetic composite particle turbid liquid in an analytical chemical laboratory is too simple to affect the convenience of related isolating operation, the scheme is that an elastic cord with elasticity is adopted for connection, so as to drag a permanent magnet protection housing internally mounted with a permanent magnet, and further form a construction member with an outline similar to a wristwatch or a boxing champion gold belt; the outer surface of the side wall of a non-magnetic container such as a glass beaker is sleeved with the member, so as to fix the permanent magnet therein; and the structure enables both mounting and dismounting to be convenient. The device is applied in isolating magnetic composite particles through a magnetic field to substitute a relative experimenter holding, pressing and positioning the slippery permanent magnet via hands with high tensity, and the device can certainly be used for small-quantity preparation of magnetic composite particles.
Description
technical field [0001] The invention relates to a chemical experiment device for isolating magnetic composite particle 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 instrumental analysis sample preparation method for the purpose of analysis and testing usually only involves tens of milligrams to several grams of micron-scale or nano-scale magneti...
