Abstract:
Solid particles combined with a water contaminated oil sample are counted by an optical particle counter. The contaminated oil sample is mixed at a substantially 1:1 ratio with a water masking solvent comprising about one part isopropanol and about three parts toluene. The oil and solvent mixture is passed through a transparent viewing volume between a light source and a light detector for detection and counting of oil suspended solid particles.
