Collidine, reagent

Fig. 1 Comparative recordings of the reflectance scans of a mixture of phenylethylamine (1), tyramine (2), serotonin (3) and histamine (4) A. ninhydrin reagent (q.v.), B. ninhydrin — collidine reagent.

The mechanism of the fluorescence reaction has not been elucidated. See Volume 1 a Ninhydrin — Collidine Reagent for the ninhydrin reaction. 

Figure 10.17 Two-dimensional high voltage electrophoresis and chromatography of amino acids. Paper high voltage electrophoresis (4000 V) in an acetic acid-formic acid buffer at pH 2.0 in the first dimension followed by descending chromatography in the second dimension in an n-butanol-acetic acid-water solvent (12 3 5). The spots were visualized with a ninhydrin-collidine reagent.
