摘要： An apparatus comprising a dynamic vapor microchamber having a recessed area that accommodates a test material that includes chemical vapors emitted therefrom; an air inlet chamber that directs a flow of air towards the recessed area; at least one air flow wall adjacent to the recessed area and intersecting the flow of air, wherein the at least one air flow wall disrupts the air flow field as it flows towards the test material and produces a uniform and distributed laminar air flow field across a surface of the test material; a thermal controller under the recessed area that maintains a uniform temperature of the test material and the flow of air over the test material; and an air exhaust port that collects the vapors emitted from the test material. The apparatus may include a plurality of chambers arranged adjacent to one another.
