Abstract

Contamination, particularly oil in water, is detected by passing the water through a cell (1) across which a laser beam is directed from a window (3) to a window (6) and to a direct detector (5). Oil droplets in the water cause scattering of the laser beam to another window (9) at an angle to the laser beam, and thence to a scatter detector (8). From the outputs of the detectors (5, 8) an output signal related to the contaminant (oil) level in the water is obtained. The output signal is applied to a sample valve trigger (16) circuit which is such as to actuate a valve to obtain a sample of the water when a predetermined contamination level is exceeded. The output can also be applied to a chart recorder (14) and a direct contamination-reading instrument (15) if desired. Thus contamination levels are monitored "on line" with provision for confirmatory chemical analysis when predetermined contamination levels are exceeded.
