Abstract
A method for deriving a calibration curve for determining a concentration of an analyte in an electrochemical reactor comprises determining a current level between a functionalized electrode and a reference electrode in the electrochemical reactor in absence of an analyte, the current level forming a zero-concentration current; injecting a fluid comprising an analyte in a first given concentration in the electrochemical reactor, determining after the predetermined amount of time a first calibration current level corresponding to the first given concentration and calculating a first current ratio of the first current level to the zero-concentration current; repeating the previous step for at least a second given concentration of the analyte, yielding at least a second current ratio of a second current level to the zero-concentration current; obtaining a calibration curve indicative of current ratio as a function of concentration from the first current ratio and at least the second current ratio.
