Analysis of Sagebrush Aromas by Headspace SPME-GCxGC-TOFMS and Utilization of Variable Modulation in the Second Dimension Separation

This novel food/flavor/fragrance application was conducted to show enhanced characterization of the aroma components released from sagebrush using headspace solid phase microextraction (SPME). The experimental method utilized comprehensive two-dimensional gas chromatography as well as variable modulation to maximize peak capacity, and chromatographic resolution for this complex sample. Analysis of this very complex sample illustrates the advantages of GCxGC-TOFMS.
