Chemical experiment device for magnetic composite particle suspension segregation program
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.
Described standby sample means can also be expressed as the pre-treatment means.
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, effect due to magnetic field, magnetic composite particle trapping agent in suspension carries its object that captures and moves, assembles to high magnetic field area together, and this moves, accumulation process continues approximately tens of 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 like this, namely, be affectedly bashful on the other hand, press permanent magnet, the described non magnetic container of another holds, carry 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 above-mentioned the whole trapping agent isolation operation process that remaining liquid topples over, 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 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
