Abstract
An apparatus (10) and a method for concentrating and transferring volatile compounds contained in a sample on a detachable solid support (12) into a liquid for subsequent detection and/or analysis of the volatile compounds, are described. The apparatus comprises a holder (14) for the solid support (12), means (16) for transporting the holder (14) to a heating position on a heatable plate (18), an enclosed space-creating arrangement comprising the heatable plate (18) attached to a movable housing (30), the holder (14), the solid support (12), a funnel (20) on the solid support (12), and inside the funnel (20) a chilled member (22), means inside the housing (30) for heating the heatable plate (18) to evaporate the volatile compounds which then are condensed on the chilled member (22), means (24) for transporting the chilled member (22) from a cooler (26) to the inside of the funnel (20) and from there to a position (28) where condensed compounds are removed from the chilled member (22) into a liquid.
