Electrochemical sensors stainless steel electrode

Electrochemical Techniques. Cyclic Voltammetry (CV) was performed on most of the poly(3-methylthiophene) anion sensor electrodes. Cyclic voltammetry provided the electrochemical characterization and evaluation of the post treatment of the modified electrodes. The potential of the platinum electrodes (Model MF-1012, BAS Inc.), with or without modifying film of poly(3-methylthiophene) was controlled relative to an Ag/AgCl reference electrode (BioanaJytical Systems Inc., West Lafayette, IN). The auxiliaiy electrode was a platinum flag electrode or in the case of the FIA experiments a stainless steel block electrode (BAS, West Lafayette, IN). 

The selection of materials and fabrication techniques is crucial for an adequate sensor function and the performance of a sensor often ultimately depends upon these factors. Consequently, future developments in sensor design will inevitably focus upon the technology of new materials. Materials used in electrochemical sensors are classified as (1) materials for the electrode and supporting substrate (metals platinum, gold, silver, and stainless steel carbon-based materials graphite, carbon black, and carbon fibre new mixed materials or organic electroconductive...
