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
The present invention relates to a kind of chemical experiment device for segregation magnetic composite particle suspension, 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 the magnetic composite particle trapping agent that has adsorbed object with permanent magnet, through having adsorbed the magnetic composite particle trapping agent of object from this, elution program isolates object again, for instrumental analysis sample introduction thereafter, this is the standby sample means of a kind of very efficient instrumental analysis among at present flourish.
The standby sample means of described instrumental analysis take analytical test as purpose only relate to tens of milligrams usually to micron order or the nano level magnetic composite particle trapping agent of number gram, and its volume of water analysis object that relates to also only has hundreds of milliliters usually to the amount of several liters.
Micron order or nano level magnetic composite particle trapping agent are scattered among the water analysis object, form suspension, with the close non magnetic container that holds this suspension of permanent magnet, because the effect in magnetic field, magnetic composite particle trapping agent in the suspension carries its object that captures and moves, assembles to high magnetic field area together, and this moves, accumulation process continues tens of approximately seconds to the number minutes; This case institute problems of concern just appears at this trapping agent isolation operation link: situation about recognizing at present is, experiment and correlation analysis operating personnel are being affectedly bashful the naked permanent magnet without any additional equipment to remove to be adjacent to described non magnetic container with hand, always like this in whole trapping agent isolation operation process, at toppling over of thereafter remaining liquid, in the discharging operation process, also be like this, namely, be affectedly bashful on the other hand, press permanent magnet, the described non magnetic container of another holds carries out toppling over of remaining liquid with a kind of relatively nervous operating attitude, discharging operation.The normally hundreds of milliliters of described non magnetic container are to several glass beakers that rise capacity, comprise in the whole trapping agent isolation operation process that remaining liquid topples over above-mentioned, equally be smooth glass and so on container wall on hard, smooth permanent magnet by being pressed in hand, carry out simultaneously described remaining liquid and topple over action, its operation tensity is apparent.If be engaged in for a long time the operation that such needs tighten one's nerve, so, it will cause to experiment and correlation analysis personnel's physical and mental health recessive infringement.
Therefore, how improving the simple operation of magnetic composite particle suspension segregation link in the relevant chemical experiment, is a problem that merits attention.
Its research and development and the application in the analytical test field of related magnetic composite particle trapping agent as an example, can be 201210099400.3 Chinese invention patent application case referring to application number.
About its research and development and the application in the analytical test field of magnetic composite particle trapping agent, also can be referring to following paper information: Zhang S X, Niu H Y, Cai Y Q, et al.Barium alginate cagedFe
