ABSTRACT:
A contaminant detector including a light source for emitting light of a wavelength with peak emission corresponding to that of "blue" light or to that of light of even lower wavelength. Light is emitted through an arrangement containing a liquid sample having a given contaminant, and a sensing arrangement on the other side of the liquid sample detects the amount of light passing through the liquid sample. The measured light is converted into a value indicative of the relative presence of the given contaminant in the liquid sample. It is contemplated that other types of light can be used, particularly if the color of the light is matched, or even approximately matched, with that portion of the liquid sample that is not to be measured (i.e. the "background" or "non-contaminant" portion of the liquid.
