## Abstract A simple flow injection amperometric system for fast and indirect quantification of dopamine (DA) in the presence of a large excess of ascorbic acid (AA) is reported. The method consists of the application of three sequential potential pulses to an unmodified glassy carbon‐working elect

A method is proposed for the flow-injection determination of ascorbic acid (0.1-40 pg ml-'). Iodine is generated in the flow system as triiodide ion or the triiodide/starch complex giving a steady spectrophotometric signal at 350 or 580 nm, respectively; inverse peaks caused by ascorbic acid samples
