Orbitrap GC-MS for Quantitative and Qualitative Multi-residue Analysis of Pesticides
Author(s)Sponsor's Content
The recent introduction of high resolution, accurate mass (HRAM) OrbitrapTM technology coupled to GC brings a new level of performance and flexibility in full scan acquisition and more. Comparable sensitivity and selectivity of triple quadrupole GC-MS/MS, but with broad scope, and the capability for simultaneous targeted and non-targeted analysis of pesticides at low ng/g concentrations, in complex sample types. In this Q & A, Paul Silcock discusses the story so far, around the use of Orbitrap GC-MS for quantitative and qualitative multi-residue analysis of pesticides.
