2. In an electroanalytical sensing experiment, a series of standard solutions are tested. For each sample solution, the electrochemical current-voltage signal is recorded and the current peak height() is measured. The standard deviation, o, measured in the blank solution is 1 PA) Determine the lowest analyte concentration one can measure the detection limit) Determine the relationship between the analyte concentration and the signal. . What is the analyte concentration when the signal is 79 pA and its uncertainty? C(MM) i (p) 0 0 0.15 4.3 03 12 0.6 23 1.5 48 ?? 79 3.0 105
