ABSTRACT:
A fluid contamination analyzer has a sample cell containing a trapping medium capable of trapping contaminants suspended in the aqueous fluid flowing through the trapping medium, a light source for illuminating the trapping medium to cause the entrapped contaminants generate a secondary radiation indicative of the identity and quantity of the contaminants, and a photodetector for receiving the secondary radiation. The fluid contamination analyzer has a reflective shell in the form of an ellipsoid extending at least partially around the sample cell and the detector, the sample cell being positioned at one of the focal points of the ellipsoid, and the photodetector at the other point of the ellipsoid to receive the secondary radiation reflected by the reflective shell.
