Enhanced aroma profiling of vodka using automated immersive high-capacity sorptive extraction with GC–MS
Application Note 261
Historically, a wide variety of sampling methods have been used to extract volatiles from alcoholic spirits, with a key driver being the need to improve upon inefficient solvent extraction methods.
One such improved method is HiSorb™ high-capacity sorptive extraction, which is a highly efficient sampling approach for a wide range of applications. It involves use of robust, inert metal probes fitted with a relatively large volume of PDMS sorptive phase, allowing high sensitivity to be achieved.
This application note shows the advantages of immersive sorptive extraction, using high-capacity HiSorb™ probes, for the gas chromatography–mass spectrometry (GC–MS) analysis of a wide volatility range of aroma compounds in vodka.
