According to the flock together principle of the single diaphragm,applying Gauss-theorem of the static electric field,the expressions of the single diaphragm electrostatic lenses focus is educed in the near axis condition,the principles of electric focusing and focusing adjusting of the Oscillograph are analysed.

Microchip free flow isoelectric focusing with immobilized pH gradient on monolithic materials

Methods:In CSF and serum from 398 patients with neurological diseases ,51 of whom had MS,OCB were detected using isoelectric focusing with immunofixation.

Methods Polyacrylamide gel isoelectric focusing followed by immunofixation techniques was employed for examining the α 1 -ACT phenotypes in 200 unrelated individuals randomly selected from the Guangzhou Han residents.

All the experiment results of the peanut protein emulsion via isoelectrofocusing then SDSPAGE, the emulsion via precipitation by ammonium sulfate of different saturation degree then SDSPAGE and the SDSPAGE of emulsion obviously show eighteen strip zones.

Studies of esterase isozymes by high resolution thin layers isoelectrofocusing were identified in different ages of cotton bollworm, Helicoverpa armigera (Hubner) larvec.

The isoenzymes in coarse laccase by extraction from raw Chinese lacquers were separated and identified by isoelectrofocusing.

The idea of using electrokinetic focusing is put forward for operation, separation and counting of microspheres in fluid.
