Extractors with electric fields

Figure 2. Schematic diagram of the imaging apparatus with ion lens. The detector is a dual microchannel plate/phosphor screen assembly (40 mm active diameter) coupled with a CCD camera. Electric field lines are shown to illustrate the ion lens. Equipotential surfaces in the repeller/extractor region are also included.

To test this method extraction of fixed human red blood cells and latex suspended in 0.01 mol 1 phosphate buffer was performed at different electric field strengths such as 0.05 Vm or 0.1 Vm. A simple mathematical model was developed (discussed in Sect. 2.2.3) to describe the mass and heat transfer during the electrophoretic separation process in the countercurrent extractor employed. The experimental results agree reasonably well with those predicted...
