The use of a chemically modified electrode for amperometric detection in flowing solutions is described. The modifier is a ruthenium‐containing polymer ([Ru(bpy) 2 (PVP) 5 Cl]Cl) that exhibits electro‐catalytic properties. The polymer‐coated electrodes are less prone to fouling (product adsorption) problems and show enhanced sensitivity for various dithiocarbamate metal complexes and nitrite ions. Limitations of the chemisorbed polymer coatings are discussed.
