ABSTRACT:
Disclosed are a method and an apparatus for determining catecholic compounds and their related compounds contained in a substance by utilizing the specific reactivity of the compounds with ferric chloride and potassium ferricyanide as reaction reagents. The reaction products are analyzed by spectrophotometry, preferably in combination with high-performance liquid chromatography, so as to determine catecholic compounds and their related compounds.
