Kinetic methods have been widely used in analytical chemistry generally using spectrophotometric or electrochemical detector however although enthalpimetric methods have been scarcely used they may offer some interesting performances like to be blind to the color and or turbidity of the samples. 131 kinetic methods versus equilibrium methods in an equilibrium method the analytical signal is determined by an equilibrium reaction involving the analyte or by a steady state process that maintains the analytes concentration. 15 kinetic methods of analysis 151 introduction this chapter contains a section for the general terms and definitions of kinetic methods as used in analytical chemistry it will be extended later with sections specifically on catalytic and enzymatic methods a kinetic method which utilizes a catalysed reaction for analysis. The earliest analytical methods based on chemical kinetics which first appear in the late nineteenth century took advantage of the catalytic activity of enzymes in a typical method of that era an enzyme was added to a solution containing a suitable substrate and their reaction monitored for a fixed time.
