Abstract:
1. An absorbance monitor for measuring a plurality of components in a sample, comprises: a light source; a sample cell; a plurality of detector units, each detector unit respectively measuring a different component in the sample; and a first light directing member mounted between the light source and the sample cell for directing a first predetermined quantity of the entire wavelength range of light from the light source to a first detection unit of the plurality of detector units and directing a second predetermined quantity of the entire wavelength range of light from the light source to a second detector unit of the plurality of detector units, wherein the first light directing member has a light truncated light passageway with a first light transmitting passageway extending at an angle to an axis of the light truncated passageway from the light truncated passageway to the first detector unit.
