were between 93.0% and 110.3% at spiked levels of 0.02, 0.1, and 0.2 μg/mL. As opposed to similar reported methods, our method showed high sensitivity and recovery; furthermore, the matrix interference was eliminated, and the chromatographic peaks of the analytes were completely separated from the impurity peaks at the level of 0.2 μg/mL. The automatic solid-phase extraction equipment is convenient to operate and allows one to process samples in batches. The conditions for solid-phase extraction can be precisely con
