Note: 1: concentration levels: 0.1, 5 and 100 ng/mL used for inter- intraday precision and accuracy (only the levels within the linear range were used for each compound). 2: 5 replicates were injected of each concentration level for each day. 3: IQL is set as the lowest linear point that has a precision of < ± 20%. 4; starred compounds denoted quality control criteria out of the acceptance range suggested by the European commission
