Screen printed electrodes are compact, disposable, and highly reproducible electrochemical platforms widely used for rapid sensing and analytical applications. This protocol provides a simple workflow for routine laboratory use of SPEs with liquid samples. It is suitable for method development, preliminary screening, educational demonstration, and analytical testing where a small sample volume and easy electrode handling are desired.
Instrument SOP
This protocol describes the standard procedure for using screen printed electrodes (SPEs) for electrochemical sensing applications. It covers electrode inspection, optional preconditioning, sample application, electrochemical measurement, and post-run handling. The procedure is suitable for carbon-based SPEs having a carbon working electrode, carbon counter electrode, and Ag/AgCl reference electrode. It can be adapted for cyclic voltammetry, differential pulse voltammetry, square wave voltammetry, chronoamperometry, and related electrochemical methods.
