Trap focusing offers a powerful solution to common challenges in headspace (HS) and solid-phase microextraction–gas chromatography (SPME–GC) analysis of foodstuffs, including poor peak shape, limited sensitivity, and restricted dynamic range. This article explores how automated cryogen-free focusing, combined with multi-step enrichment and re-collection capabilities, can improve the detection and quantitation of both aroma-active compounds and trace-level contaminants. Using real-world examples, including flavor profiling of cola and garlic, and quantitation of ethylene oxide and epichlorohydrin in spices, enhanced chromatographic performance, greater confidence in compound identification, and lower detection limits than traditional workflows such as direct SPME or QuEChERS (Quick, Easy, Cheap, Effective, Rugged, and Safe) are demonstrated.
