title: A sensitive double isotopic, chromatographic method for the determination of histamine. I: Studies with authentic histamine.
abstract: This paper presents a method for the determination of histamine using an internal standard of 14C-labelled histamine, which together with an unknown sample of unlabelled histamine is dansylated with 3H-labelled dansyl chloride. The products of this dansylation are then separated on thin-layer-chromatographic plates coated with micropolyamide. The spot of dansylhistamine is scraped off and the content of histamine in the unknown sample is calculated from the 3H/14C-ratio in the spot.
