- The accuracy (%) was calculated by comparison with the target concentration weighed during sample preparation
- aThe target concentrations were selected as 10, 20, and 30 μg/mL for non-diluted samples and 300 μg/mL for samples needed dilution
- The data are presented as mean ± SEM from four independent measurements
