Figures of merit of the proposed method.
| Figure of merit | Fe | Mn |
|---|---|---|
| Linearity (studied for this application) | up to 5.0 mg L−1 | up to 2.0 mg L−1 |
| LOD (mg kg−1) | 2.6 | 0.06 |
| LOQ (mg kg−1) | 7.7 | 0.19 |
| Precision (%RSD, n = 6) | 4.7 | 5.0 |
| Trueness (%R, n = 6)a | 82.5 ± 4.9 | 107 ± 5 |
Mean ± standard deviation; LOD: limit of detection; LOQ: limit of quantification (dry basis).
