Advancements in the hybrid Qq-TOF instruments provide the ability to perform targeted and non-targeted multi-residue
screening and Quantitation on a routine basis. Such instruments provide high resolution, accurate mass MS and MS/MS
information enabling high quality screening for virtually every known chemical, identify and quantify undesirable contaminants
using MRMHR quickly and easily. Resolution > 20,000 (at full width half height) and mass accuracy <5 ppm is often sufficient
to separate the analytes of interest from interfering matrices and, thus, is a requirement for compound identification in various
guidelines (EU Commission Decision #2002/657/EC; SANCO Document: #SANCO/10684/2009). High resolution MS and MS/
MS data allows generating very narrow XIC window of 10 to 20mDa for both parent as well as product ions. This capability
provides adds an additional level of selectivity for any chemical residues in complex samples for targeted analysis workflows
resulting in the best Signal-to-Noise ratio. High confidence in results will be based upon retention times, accurate mass, isotopic
pattern and MS/MS library searching. This presentation will cover a) the unique HRMS workflows for multi-residue screening,
b) the benefits of MRMHR for routine high resolution Quantitation for food contaminants.
