| Abstract: | The method is based on formation of the fluorescent condensation products with o-phthaldialdehyde; 0.5–2000 ng ml?1 histamine and 3–700 ng ml?1 spermidine can be quantified, with relative standard deviations of 2–3%. Histamine/spermidine ratios of 2.5:1–1:30 can be handled. A selectivity study is reported. |
