According to the gradient dilution technique of flow injection anal., in combination with accurate time lag as well as quick collecting and handling data supplied by microcomputer, a new method for the determination of composition of complexes by only injecting a single standard solution of the metal ion and matching parts sep. under nonequil. state is described. By means of the determination of some complexes, the experimental results have shown that the method is simple, quick and with good accuracy and suitable for both stable or nonstable complexes.t
