Example 2

A sample volume of creatinine sample of 300 uL is placed on the electrode having the FeCl3 receptor of 0.6 mg then the peak reduction current value is noted from cyclic voltammogram specifying a potential window from 0.6 V to −1.0 V with scan rate of 0.1 V/sec in CHI Electrochemical workstation. The value of peak reduction current is measured as 105 μA. The presence of this current value is searched in the values as provided in Table 1 and the corresponding concentration of urine creatinine is retrieved, which is 240 mg/dL.
