The study of exchange reaction kinetics between sulfur-35 and organic compounds which contain sulfur can be made much easier by use of radiochromatography. Activity ratios of the components of the reaction mixture can be estimated by use of very small amounts of radioactive materials. The reaction need not be halted and individual components need not be isolated. Any degradation of reacting substances can be measured quantitatively at the same time.
