Evolution of the analytical signal in electrochemistry from electrocapillary curve to a digital electrochemical pattern of a multicomponent sample

The number of publications on the electrochemical analysis liquids increases year by year. growth publication activity is largely due to development new biosensors and introduction nanomaterials into practice analysis. It not task author review entire array publications, since basic principles in most remain practically unchanged. purpose this critical find answers two important questions for electroanalysis. First, are all used methods providing a measurement strict metrological sense term? That is, do they provide necessary accuracy, validity, reliability, reproducibility results? Secondly, electroanalytics capable meeting challenge information revolution significantly increasing efficiency each individual measurement? To answer these questions, we will identify main sources sensor signal noise considering as primary decoder “chemical information” an analytical signal. Then evaluate various using approach thermodynamics processes open thermodynamic system.
