Abstract
A rapid, automated method for the determination of organic halogens is provided by an analytical system comprising a burner and combustion chamber for burning the organic halogen-containing sample in an oxygen-hydrogen flame; an absorption zone wherein the combustion gases are absorbed in a moving reagent film; and a colorimeter and recorder. With proper choice of reagent film, either total halogen (Cl, Br, I) content or specifically bromine content can be assayed automatically. The system is particularly useful for analysis of biological samples.
