Abstract

An optical monitoring system for determining the constituents of a sample or specimen. An absorption spectrum is obtained from a sample and is passed through one or more filters having a specified absorption spectrum defined by a single atom or a compound. If the filter's absorption spectrum is included in the sample's absorption spectrum, then the sample contains that atom or compound. The apparatus includes a switching assembly that sequentially places one or more filters into the light path to determine if the subject atom or compound is contained in the sample.
