Calibration plot of Moxi in a urine sample prepared in B-R buffer solution (pH 7.0) using GNMSPE. Inset A: separate detection of 200 µM Moxi with 200 µM paracetamol by DPV in the same solution. Inset B: I) calibration plot for Moxi in the presence of 200 µM paracetamol, and II) calibration for paracetamol in the presence of 200 µM Moxi. Inset C: detection of 200 µM Moxi alone or in the presence of 200 µM ascorbic acid, dopamine, uric acid or estradiol).
