What is Kinetic Determination of Adrenaline, L-dopa and Their Mixtures with a Stopped-flow Spectrophotometric Technique about?

## Catecholamines (adrenaline and GDopa ) can be determined by a stopped-flow spectrophotometric technique. For individual determinations, catecholamines are oxidized to the corresponding o-benzoquinones by hexachloroiridate(IV). Concentrations in the range 2-10 "-2 lo-" M can be determined with errors of about 2 %. For evaluation of mixtures, aminochromes are formed. The method allows a catecholamine concentration of about 5 -10" M to be determined in the presence of a ten-fold amount of another catecholamine, with a maximum error of about 10 %.
