The present invention is directed to a process for purifying siloxane. A high frequency electrode is embedded in the insulating ceramic base in the vicinity of the heating surface, and a heating body is embedded in the base in a location that is further from the heating surface than the location of the high frequency electrode. Constantly updated location information for mobile stations in communication with a switching center is maintained in a database that can be accessed by PSAP agents on an \u201cas needed\u201d basis. 3, a halide content of less than 1 ppm and a metal content of less than 500 ppm, making it useful for current and future microelectronics applications. The accumulating charge makes the device far more efficient than a conventional Wimshurst generator.
