摘要
A method of vapor sampling and its delivery to the porous sensory element(s) employed in chemical detectors/sensors for vapor(s) identification and quantification. The sampling and delivery system comprises a flow cell in which a sensory membrane is placed parallel to the flow, while an additional flow normal to the membrane is introduced using the Bernoulli effect. The bi-directional flow of vapors increases the interactions between the sensory material and vapor molecules, and enhances sensitivity.
