Abstract

A method of and apparatus for examining substances by subjecting them to a gravitational field while measuring the electrical effect derived from any resulting charge orientation. A centrifuge is preferably employed to give high g forces and an electrode system is used to provide an output signal. The output signal can be plotted against changing g forces to give a gravitational spectrum analysis graph. An apparatus for using such method is also described. Said apparatus comprises a direct or capacitive electrode system with one or more electrodes made of noble metal.
