Abstract: A multiple path spectrophotometer system is disclosed in which the beam from a radiation source is selectively directed over a plurality of different paths which may contain sample material or reference material and is detected by a single detector. The radiation source is operable to provide a beam at a plurality of alternately selectable wavelengths and the detector detects the absorption effects of material within the selected path. The method uses three sequential paths in which one path has negligible absorption, one has known selective absorption and one has unknown selective absorption to be determined.
