Calculated electrode areas (Areal) for SPEs using the Anson plot equations (Equations (6) and (7)) recorded at 19.6 °C for each redox probe, with the diffusion coefficient used in the calculation. The %Real, which is the percentage of Areal divided by the Ageo, is also presented (N = 3).

| RuHex | 0.055 | 9.40 × 10−6 | 73.34 |
| NADH | 0.077 | 7.40 × 10−6 | 103.27 |
| Dopamine | 0.077 | 6.74 × 10−6 | 102.51 |
| Capsaicin | 0.057 | 7.03 × 10−6 | 75.91 |
| TMPD | 0.053 | 6.32 × 10−6 | 70.53 |
| Ascorbic acid | 0.121 | 1.42 × 10−6 | 161.21 |
