These are then put into a gas chromatograph, which separates the chemical components.

This allows the evaporates to be collected on a small trap which is then transferred to a gas chromatograph.

This is not the first time the gas chromatograph analogy has been used for nasal anatomy.

The scientists hypothesize that this structure may function like a gas chromatograph—a sophisticated chemical device that separates different compounds based on their solubility.

Previous investigations have shown that other exquisite smellers, including dogs, rats and bobcats, have a nose with coiled turbinates, but the new paper is the first to study the arrangement in house cats and extend the gas chromatograph analogy to mammals.
