Abstract
A method for restoring a volatile compound from a trapping means, wherein the method includes a flowing step wherein a carrier gas flows through the trapping means, at a controlled rate, by increasing the volume of a chamber located downstream of the trapping means is disclosed. The invention also relates to a device for implementing the method. The invention allows to faithfully restore the compounds that have been previously trapped and to faithfully restore the trapped odors.
