Application Note: Comparing GC/QQQ To GC/Q Methods for the Analysis Of Pesticide Residues In Fruits And Vegetables

• 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.
