Assessment of intra-day and inter-day precision of the proposed method.
Drug | % Recovery* ± RSDa | |
---|---|---|
Intra-day | Inter-day | |
KPN (3.0 μg mL−1) | 100.26 ± 1.27 | 99.79 ± 1.65 |
PAR (1.0 μg mL−1) | 99.92 ± 0.96 | 100.16 ± 1.79 |
CLX (5.0 μg mL−1) | 99.86 ± 1.03 | 100.65 ± 2.18 |
Average of three determinations, RSD is relative standard deviation.
