Abstract

A rapid desorption device for magnetic nanospheres is disclosed, belonging to the technical field of instruments for analytical chemistry. The device includes an electric pushing bar, a motor, a desorption cell, an electromagnet coil, a magnetic sleeve bar, a vertical plate and a controller. According to the structure, the motor and the electric pushing bar are mounted at the vertical plate separately and in parallel with the vertical plate; the center lines of the motor and the electric pushing bar are parallel; the motor is fixed by a motor rack; a motor shaft is connected to a cell seat inwhich the desorption cell is arranged; the electric pushing bar is fixed to the vertical plate through bolts; the pushing bar upper end of the electric pushing bar is fixedly connected to a pushing bar fixing clamp through bolts; the pushing bar fixing clamp is fixedly connected to the magnetic sleeve bar; the lower end of the magnetic sleeve bar is provided with an electromagnet sleeve in which the electromagnet coil is mounted; and the electromagnet coil, the motor and the electric pushing bar are connected to the controller respectively through a wire. Up-down reciprocating motion of an electromagnetic head and rotation in a rotary cell can accelerate adsorption of magnetic nanospheres to the electromagnetic head, with adsorption being completed in 10 s, and the magnetic nanospheres areimmediately released to a solution when power supply interruption occurs.

Description

technical field [0001] The invention relates to a fast desorber of nanometer micro magnetic spheres, which belongs to the technical field of analytical chemical instruments. Background technique [0002] At present, the surface of the known nano-micro-magnetic balls can be quantitatively adsorbed to target compounds after modification. After the nano-micro-magnetic balls are adsorbed and separated from the target compounds, a permanent magnet is attached to the outside of the centrifuge tube to absorb the magnetic balls and separate from the matrix solution. Remove the permanent magnet and use a desorption solution After desorbing the target compound, it is detected by other methods. This method is slow and needs at least 5 minutes, and the separation is not complete due to the long distance between the nano-magnetic microspheres and the magnet. Contents of the invention [0003] In order to overcome the above-mentioned technical deficiencies, the present invention provid...
