Overcoming limitations in food analysis with cryogen-free trap focusing
LCGC: The Column, Sept 2025
Curious how to boost sensitivity and confidence in food VOC and SVOC analysis without the cost and logistics of cryogens?
This article shows how cryogen-free trap focusing elevates headspace and SPME–GC–MS workflows, sharpening early-eluting peaks, widening dynamic range and cutting operator time. Using real-world matrices – from cola and garlic flavour profiling to trace-level fumigants in spices – the authors demonstrate clearer separations, stronger library matches and quantification down to 0.005 mg/kg, all within automated methods.
While the examples focus on food, the same principles apply across wider HS/SPME–GC–MS workflows in fragrance, consumer products and environmental monitoring.
If you’re aiming to simplify sample preparation, increase throughput and meet tightening regulations with reproducible data, this is a concise, application-led read.
