Abstract: New and improved fluid supply control method and apparatus for periodic fluid merger which are particularly adapted to the periodic, precisely timed introduction of precisely and uniformly sized fluid segments into a fluid stream are disclosed and comprise a segmenting fluid supply line which respectively connects with a pressurized source of said segmenting fluid at substantially constant pressure and with the line in which said fluid stream is flowing. First and second, quick-acting flow interrupting means are operatively associated with said fluid supply line at spaced locations thereon, and a cavity of substantially constant volume is formed between said flow interrupting means. In operation, and for the formation of each of said segments, said first flow interrupting means are opened to effect the filling of said cavity with said pressurized fluid whereupon said first flow interrupting means are closed and said second flow interrupting means opened to effect the flow of said pressurized fluid from said cavity into said fluid stream to form said segments. A form of the invention is disclosed wherein said fluid supply line is constituted by a compressible, resilient tube and said flow interrupting means comprise means to compress and close said tube at spaced locations thereon. In this disclosed form, the cavity is formed by the volume of the tube which extends between said flow interrupting means.

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.
