Cleanliness verification system

摘要

A method for detecting contaminants on an implement. A stream of gas is directed over at least a portion of the implement, to entrain at least a portion of the contaminants on the implement, and produce a contaminant laden stream of gas. At least a portion of the contaminant laden stream of gas is sampled, and the amount of contaminants in the sampled portion of the contaminant laden stream of gas is measured. The amount of contaminants in the sampled portion of the contaminant laden stream of gas is reported.
