ABSTRACT:
An automatic photometric analyzer is disclosed using an automatic exchanger holding a sample solution. A recorder, a photometer, an injector for the sample solution, and supply systems for pure water and coloring solutions are used. Additionally, valves under control of an automatic controller properly control the flow and the solution to provide a simple and practical apparatus with rapid automatic operation for analysis. The injector delivers reactant solutions to a reactor from which reactant is circulated through the photometric means to measure the absorbency thereof and back to the reactor.
