Sodium borohydride, in place of stannous chloride or titanous chloride, is effective in the preparation of the ninhydrin reagent for automated amino acid analysis. The reagent, coupled with dimethyl sulfoxide as a solvent, a very stable ninhydrin solution which did not form precipitates in the flow lines of the analyzer.
硼氢化钠可替代氯化亚锡或氯化钛，用于制备用于自动氨基酸分析的茚三酮试剂。该试剂与二甲亚砜作为溶剂配合使用，形成了一种非常稳定的茚三酮溶液，该溶液在分析仪的流路中不会形成沉淀。
