Abstract: New and improved method and apparatus for the time sharing of multiple channel fluid sample analysis means are provided and comprise operatively associated light source, light sensitive detector means, digital logic means, detector and logic means timing and control means, detector circuit means, multiple channel fluid sample analysis result read-out means and read-out means timing and control means, respectively, said detector means is constituted by a single light-sensitive detector means in the nature of a photo-multiplier tube, and said detector circuit means comprises a single, temperature stabilized log diode and amplifier. An embodiment is disclosed wherein said light source is automatically and precisely tunable light source. In operation, the apparatus is effective to repeatedly scan said multiple channel analysis means and provide simultaneous recordings of the analysis results which are linear with regard to the respective fluid sample optical densities on said analysis result read-out means. The apparatus is applicable for use with multiple channel analysis means which include only colorimeters, and for use with multiple channel analysis means which include colorimeters and fluorimeters. The advantageous disposition of the analysis means on the manifold of operatively associated fluid sample supply and treatment means is also made possible by the apparatus of the invention.
