ABSTRACT:
This application is directed to a high-voltage electromotive process to excite a chemical species, which includes orientating, re-positioning and transporting and for the separation of chemical species on a support. Unlike conventional semiconductive technology in the solid state and amorphous state, the present process is directed to electrically induced molecular transport in semiconductive media, as distinct from charge transport.
The process of this invention is characterized by a high mobility rate in the separation process which is achieved by tailoring a semiconductive medium for operation at very high voltages and low current density. The voltage applied is preferably in excess of 50 volts/cm and as high as about 25,000 volts/cm. The semiconductive media used in this invention generally comprise several components which are chosen to give a current density in the range of about 0.2 to 100 micro amp/cm.sup.2 on filter paper as a substrate. The media should also have a high boiling point. The transport range for this separation process is from about 1 cm/sec to 0.25 cm/min. A further aspect of the process is that an external cooling means is not ordinarily required.
