Headspace technology

<h2 id="equipment">Equipment</h2>
<p>The headspace equipment involves a hollow dome or sphere-like objects which forms an airtight seal and surrounds the objects of interest. Inert gases are passed into the space containing the object or a vacuum is established such that the odor compounds are removed from the headspace.<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> These compounds are in turn captured using a variety of techniques, among them cold surfaces, solvent traps, and adsorbent materials, with the latter techniques capable of longer periods of collection. The samples can then be analyzed using techniques such as <a href="/facts/Gas_chromatography/kwLY8vt1">gas chromatography</a>, <a href="/facts/Mass_spectrometry/RH5WBHJ2">mass spectrometry</a>, or Carbon-13 <a href="/facts/Nuclear_magnetic_resonance/pGYAn9Bz">NMR</a>.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a>
