the air surrounding an odorous object, whose volatile molecules are sampled to reconstruct its scent.

In fragrance analysis, the headspace is the volume of air immediately surrounding an odorous object, and headspace analysis samples the volatile molecules in that air to reconstruct the scent, letting a chemist capture the living smell of a flower without picking it. Kolb and Ettre's Static Headspace-Gas Chromatography sets out the theory and practice of sampling the vapour phase above a sample and resolving it by gas chromatography. The referent here is the odour-laden air captured and profiled to recreate a scent, measured as a chromatographic fingerprint of volatiles. The same word in firearms means a mechanical gap and in packaging a design void, both separate constructs.[1]
