The Column
Solid-phase microextraction (SPME) coupled with comprehensive two-dimensional gas chromatography and time-of-flight mass spectrometry (GC×GC–TOF-MS) can be used to detect trace-level fungicides and compounds responsible for undesirable attributes known as “organoleptic faults” in wine. This article explains more.

The development of a novel trapping system and a modified GC–MS layout (using dual chromatographic columns and cryogenic focusing devices) has enabled a major improvement in the chromatographic separation of volatile and semivolatile compounds in cigarette smoke. This improvement has led to the potential for identifying compounds which are usually masked by the solvent peak.
