Analytical Methods for Electrochemical Sensors

Analytical techniques have been increasingly deployed for several qualitative and quantitative probe requirements in recent years. This led to a significant advancement of viable analytical methods. Amongst the available probes, electroanalytical tools have emerged as one of the most prominent contributors to analytical sciences since they offer a variety of possible methods as per the need and nature of required information. Thus, it is crucial to understand the fundamentals, applicability, and potential of electrochemical techniques to make an informed decision based on the assay’s requirements. Therefore, this chapter is focused on introducing the reader to several electrochemical sensing methods, including voltammetry, amperometry, conductometry, potentiometry, and how they can be used to determine analyte characteristics, the nature of redox processes, detection limits, calibration plots, sensitivity, selectivity, repeatability, and other relevant parameters. To summarize, a complete experimental guide for in-depth sensing is presented in this chapter, including how and when to use these methods for full-proof electrochemical sensing of the analyte.
