A NOVEL NINHYDRIN REAGENT FOR ANALYSING NITROGEN-CONTAINING COMPOUNDS |
摘要 |
A ninhydrin reagent for use in a method for analysing nitrogen-containing compounds, in particular visualising nitrogen-containing compounds by a colour forming reaction, is provided, the ninhydrin reagent comprising ninhydrin; an aqueous buffer; and a temperature-dependent reducing agent, which agent is inactive in the reduction of ninhydrin at a first temperature and active in reducing ninhydrin to hydrindantin at a second temperature, wherein the second temperature is higher than the first temperature. The reagent is particularly useful in the analysis of amino acids. |
