METHOD AND APPARATUS FOR DETERMINING OIL MIST IN COMPRESSED AIR

摘要

A test kit and method for determining in a semi-quantitative manner the amount of oil mist in a compressed air stream, which method comprises bleeding a small sample from the compressed air stream containing oil mist whose concentration is to be determined; directly impinging the compressed-air stream so bled for a defined time period through a defined orifice onto the surface of a coated plate containing an ultraviolet radiation indicator to capture the oil mist particles in the compressed air stream, thereafter comparing the test plate with a standard plate of known concentration of oil mist under ultraviolet radiation to determine the degree of fluorescent quenching as an indication of the amount of oil mist in the compressed air stream.
