Abstract

A spectrographic analysis method which is photometric and non-contact for determining the presence of a chosen constituent in water is provided based on the fact that the inverse of reflectance is a measure of absorption. A full spectrum measurement of the reflectance of the water is made and an absorption spectrum calculated which is then fitted to a clear spectrum in a wavelength range where the water absorption dominates so as to have scaling and offset. Then the clear water spectrum is subtracted and a matching is repeated for the spectrum of the desired constituent and thus a measure of the concentration of the constituent in the water is obtained.
