A kinetic method for the simultaneous determination of magnesium and calcium ions in solution is described. The method is based on the dissociation reactions of cryptand (2.2.2) complexes; a stopped-flow injection technique is used with spectrophotometric monitoring of the phthalein complexone compl

Reactor replacement is proposed as means of realizing different sample residence times in flow-injection analysis. As an application, an improved spectrophotometric determination of cobalt and nickel is proposed. The method exploits differences in reaction rates between cobalt and nickel citrate com
Quantitation of proteolytic enzymes using N-succinyl-L-Ala-L-Ala-L-Pro-L-Phe-p-nitroanilide has been adapted to flow-injection analysis. This procedure has been developed using two different proteases: subtilisin and chymotrypsin. For both enzymes the influence of substrate concentration on spectrop
