Abstract
Gas chromatography coupled to mass spectrometry and olfactometry (GC-MS/O) is a methodology widely applied in the material industry to establish correlation between the chemical nature and concentration of specific odorous compounds. However, some materials may produce very complex VOC profiles and make it difficult to identify odor active compounds. This phenomenon is accentuated with the emergence of recycled materials.
Comprehensive two-dimensional gas chromatography coupled to high resolution time-of-flight mass spectrometry (GC×GC-HRTOFMS) has been identified as a powerful tool to characterize complex VOC profiles. The HRMS is required not only for the identification of unknowns but also as a third dimension to increase sensitivity and selectivity and allow detection of odorous compounds at trace levels, specific from materials.
Practical examples will be presented to demonstrate the useful complementarity of this advanced technique for the characterization of material emissions and the evaluation of processes for odor reduction.
