Identification of Off-Odor Compounds in Paper Products using Thin Film Solid Phase Microextraction (TF-SPME) and GC-MS/O



In this study, Thin Film Solid Phase Microextraction (TF-SPME) with a divinylbenzene/polydimethylsiloxane coating (DVB/PDMS) was used to extract off-odor compounds from paper product samples. The use of gas chromatography-mass spectrometry directly coupled with olfactory detection (GC-MS/O) enabled simultaneous detection of off-odor regions of the chromatogram and mass spectral identification of off-odor compounds. Identification of off-odor compounds in consumer goods is crucial for the manufacturer in order to identify the cause, take corrective action, and thereby maintain brand acceptance and success.
