ALLISON METHOD OF CHEMICAL ANALYSIS
Abstract
The report describes the theoretical study and experimental circuit investigations conducted on the Allison effect apparatus used for chemical analysis. The inherent electrical behavior of an Allison effect apparatus was well defined by using modern high speed oscillographic techniques and frequency selective equipment. A continuous radio frequency spectrum characterized by numerous resonances rapidly diminishes into the noise level at 4000 megahertz. A theoretical analysis of the apparatus generated a valid equivalent circuit model. A review of the extensive data indicates that the Allison effect apparatus functions primarily as a phase comparator for radio frequencies in the 30 to 100 megahertz range. An rf-optical interaction in the cells, possibly by means of the Cotton-Mouton effect, is thought to produce a characteristic light modulation effect when phase matching occurs.
