pH Sensor Benchmarking: A Protocol to Characterize pH Sensing Materials and Systems (Small Methods 2/2019)

Intrinsic contributions of commercial electrical components, reference electrodes and buffers, time plots for extended gate field effect transistor, and effect of an instrumentation's input resistance on pH sensing systems are experimentally demonstrated by Canan Dagdeviren and co‐workers, as described in article number 1800265. Critical issues, such as arbitrary drift, response time, and sensitivity calculations, facing the standardization and benchmarking of pH sensing materials, and systems, are discussed. Recommendations toward a conventional standard protocol are provided.
