A method based on in-syringe dispersive solid phase extraction (IS-D-SPE) and ultra performance liquid chromatography Orbitrap high resolution mass spectrometry for the multiresidue analysis of 117 pesticides in tea was developed. Full scan mode was acquired over an <i>m</i>/<i>z</i> range of 100-800 with Orbitrap resolution at 70000, followed by full scan/dd-MS<sup>2</sup> mode for confirmation. The identification criteria of retention time and mass accuracy tolerance was ±0.20 min and ±5.0 ppm ...[more]
