Method and apparatus for the time sharing of multiple channel analysis means

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