In this application note, a multi-residue analysis method for the detection of 212 pesticides in okra is presented.

The combination of ACQUITY UPLC H-Class System with the Xevo TQD tandem mass spectrometer can detect pesticides below the legislative limit in okra samples.  Even though a strong matrix effect was observed for many compounds, detection and quantification at the legislative limit was achieved. Simultaneous acquisition of MRMs and RADAR full-scan data provides quantitative and qualitative information in single injection.  Product ion confirmation (PICs) increases confidence in compound assignments, which proves highly useful when working with complex matrices.
