Glassy carbon working electrode for the detection of dopamine. A) Image showing the flangeless fitting with a 2 mm palladium pseudo-reference and a 1 mm glassy carbon working electrode; B) flow injection analysis to show selectivity of a Nafion-coated glassy carbon electrode; i) Response for dopamine [100 μM] using the Nafion-coated glassy carbon electrode; ii) Response for nitrite [100 μM] using the Nafion-coated glassy carbon electrode; iii) Response for nitrite [100 μM] using a non-modified glassy carbon electrode.
