Separation and determination of catecholamine in food by electrochromatoscanning method

A new electrochromatoscanning method has been developed for the quantitative analysis of the paper chromatography of catecholamine in food. This method has the characteristic advantages of both paper chromatography and electrochemical quantitative detection. It is simple, convenint, inexpensive and sensitive for organic compound analysis. This paper presents a new approach to the elctrochromatoscanning method for bioanalytical chemistry, and makes possible the quantitative analysis of catecholamine in biological substances, such as bananas.
