Summary. A fluorimetric method for the determination of dopamine is described. The principle is similar to that employed in the tri‐hydroxyindole method for estimating adrenaline and noradrenaline. Utilizing differences in fluorescence characteristics at pH about 5.3, microquantities of dopainine can be determined in the presence of at least equal amounts of adrenaline or noradrenaline.
Carlsson et al. (1958) studied this question.
