Abstract

PURPOSE:To make possible the accurate detection of contamination of even a liquid sample, through which transmission of light is difficult, so that the quantity of light emission is maintained at a constant value at all times regardless to the variation in light source or deterioration with age, whereby a contamination detector for liquid which is easy to carry and is capable of maintaining measurement accuracy for a long period of time is obtained.
