Abstract

A system and method for using a spray/liquid particle count (LPC) to measure particulate contamination is disclosed. Initially, a component for particulate extraction is received. A sprayer is provided for spraying a liquid on the component. In addition, a container is provided for catching the liquid spraying on the component. The container is clean prior to receiving the liquid and the liquid is collected for later analysis of a number of particles extracted from the component.
