Stacking Multiple SPME Extractions to Connect Olfactory and GC-MS Data

This application note highlights how stacking multiple SPME extractions with GC-MS and GC-Olfactory can improve detection of low-level analytes in complex samples, such as beer, allowing researchers to identify compounds that might otherwise go unnoticed. It demonstrates the value of sensitive techniques for revealing impactful analytes that contribute to aroma profiles even at trace levels.
