Abstract

In this technical note the often overlooked issue of electrically connecting screen-printed electrode sensors is considered. The electrical connection of screen-printed electrodes to the potentiostat/electronics can be a main issue when a true electrochemical response is trying to be obtained and if one does not have a stable electrical connection, the results that are obtained may lack reproducibility and therefore maybe discredited as ``another failed electrochemical probe/analyte{''}. This paper considers the case of electrically connecting screen-printed with crocodile clips and compares that to the use of edge-connectors demonstrating the precise connection of an electrode setup when utilising crocodile clips can result in extremely reproducible electrochemical outputs when applied correctly.
