What defines an Aroma? Advanced GC-MS strategies for fragrance characterization and off-odor analysis

What makes an aroma or fragrance appealing, distinctive—or problematic? Often, the answer lies in trace-level volatiles hidden within highly complex sample matrices. Traditional analytical methods often struggle to isolate these crucial compounds, leading to incomplete data, unresolved quality issues, and delays in product development.

From uncovering the chemicals behind the rotting corpse smell of the Rafflesia carrion flower to characterising the rich aroma of oud incense, tracking fragrance changes in air fresheners over time, and identifying off-flavours in beauty supplements, we'll showcase how our portfolio addresses a diverse range of aroma analysis challenges.

Join experts from the University of Oxford and Markes/SepSolve to explore how advanced GC–MS workflows are being used to solve these challenges and deepen our understanding of aroma chemistry, from pinpointing the root cause of product odors and defects, to tracking fragrance changes over time and understanding what we are exposed to during real-world use.
