ABSTRACT:
A method of separating soap fibers from the liquid phase component of grease to prepare the fibers for microscopic analysis includes the steps of admixing a sample of the grease with a solvent to remove the liquid phase component from the fibers and provide a final liquid product having the fibers in suspension therein, contacting the final product with a pair of spaced electrodes, applying a direct voltage across the electrodes to charge the same positive and negative respectively, and withdrawing for analysis a small quantity of the final product from a region thereof proximate the negative electrode after the voltage has been applied for a predetermined energization period. The withdrawn quantity may be deposited on a polished carbon stub and further prepared for analysis by a scanning electron microscope.
