An automatic on‐line solid‐phase extraction with ultra‐high performance liquid chromatography and tandem mass spectrometry method was developed for the simultaneous determination of ten antipsychotics in human plasma. The plasma sample after filtration was injected directly into the system without any pretreatment. A Shim‐pack MAYI‐C 8 (G) column was used as a solid‐phase extraction column, and all the analytes were separated on a Shim‐pack XR‐ODS III column with a mobile phase consisting of 0.1% v/v formic acid in water with 5 mM ammonium acetate and acetonitrile. The method features were systematically investigated, including extraction conditions, desorption conditions, the equilibration solution, the valve switching time, and the dilution for column‐head stacking. Under the optimized conditions, the whole analysis procedure took only 10 min. The limits of quantitation were in the range of 0.00321–2.75 μg/L and the recoveries ranged from 75.9 to 122%. Compared with the off‐line ultra‐high performance liquid chromatography and the reported methods, this validated on‐line method showed significant advantages such as minimal pretreatment, shortest analysis time, and highest sensitivity. The results indicated that this automatic on‐line method was rapid, sensitive, and reliable for the determination of antipsychotics in plasma and could be extended to other target analytes in biological samples.
