Pesticide residues remaining in or on commoditiesraise concerns for food safety and environmentalimpact. Regulatory agencies have published policystatements to guide agricultural organizations on theproper use of pesticides and established MaximumResidue Limits (MRLs) of pesticides in various foodmatrices. Thus, there are widely demands for highlysensitive and robust platform for the quantification ofpesticide residues analysis..
The Thermo Scientific iCAP Qs ICP-MS has demonstrated the high sensitivity and freedom from background interferences required for the measurement of particles in ambient air. The iCAP Qs ICP-MS has flexible scan times with a data buffer system capable of handling the large amounts of data acquired during long term in-situ analyses. QCell technology eliminates interferences whilst ensuring high sensitivity even for the lower mass isotopes thanks to its high transmission efficiency. A single mode KED approach could thus be employed for a number of isotopes across the mass range.
