LCGC, Amadeo Fernandez-Alba
Comprehensive testing for the presence of pesticide residues in food requires the application of both liquid chromatography (LC) and gas chromatography (GC) coupled to mass spectrometry. In particular, interest is growing in the use of full-scan High-Resolution Accurate Mass (HRAM) mass spectrometry (MS) such as the Thermo Scientific™ GC Orbitrap™ MS system for both the quantitation of target pesticides and non-targeted screening of unexpected pesticides, simultaneously in a single workflow. Historically, developments in GC-HRAM-MS have lagged behind those in LC-HRAM-MS, but the adoption of GC-HRAM-MS
has been increasing recently. LCGC spoke with Prof. Amadeo R. Fernández-Alba, PhD, professor at the University of Almería in Spain, to share his thoughts on developments in GC-HRAM-MS technology and the prospects for the use of these powerful instruments for routine analysis in the future.
