Poster: Comparing GC/QQQ To GC/Q Methods For The Analysis Of Pesticide Residues In Fruits And Vegetables

By Chris Sandy and Chin-Kai Meng, Agilent Technologies

• High temperature source (up to 350oC) and quads (up to 200oC) reduce maintenance
• GC/QQQ method was developed for >300 pesticides
• GC/QQQ MRM method compared to GC/MS in SIM and Scan (using Deconvolution Reporting Software)
• The selectivity of the GC/QQQ MRM method improved pesticide detection limits considerably over either GC/MS method
• Column backflushing kept the source and GC column clean, reducing maintenance
