Headspace
Headspace analysis samples the aroma around a flower or object. Learn how it guides perfume reconstruction and why a chemical reading is not a bottled extract.
Updated
Headspace is the air or vapor above or around a material. In perfumery, headspace analysis samples the volatile substances a flower, fruit or other source releases into that space, then analyzes the sample to learn about its scent.
The information can help a perfumer reconstruct an impression using available aromatic materials. The analysis is not itself a bottle of flower extract, and detecting a compound does not tell you exactly how much it contributes to the perceived smell.
The approach can study a living source without harvesting it, depending on the sampling arrangement. Timing and conditions matter: the air sampled around a flower is a snapshot of its emissions, not a complete and permanent recipe for its scent.
- Headspace sample
- Volatile material collected from the space around a source for analysis.
- Adsorbent
- A material that traps compounds on its surface, used in some sampling methods.
- GC-MS
- Gas chromatography–mass spectrometry: a combined method for separating compounds and helping identify them.
- Reconstruction
- A formulated scent inspired by analytical and smelling work. The perfumer still makes choices about materials and balance.
- Headspace vs. extraction
- Headspace work studies emitted volatiles. Conventional extraction recovers aromatic material from the source itself for use as an ingredient.
