Abstract

See full text

A substance detection device, including a chemical substance analyzer, including an ion mobility spectrometer (IMS), a desorber, a conduit, and a membrane. The membrane extends across a cross-section of the conduit, and the membrane is positioned to have a desorber side in gas communication with the desorber and an analysis side opposite the desorber side. The substance detection device can be configured to direct a portion of a chemical substance to the desorber through the conduit so that at least a portion of the entrained chemical substance is transferred to the membrane by interacting with the desorber side of the membrane. The membrane is adapted to diffuse at least a portion of the chemical substance transferred to the membrane through the membrane to the analysis side. The device also includes a particle separator including a protuberance extending into a collection chamber of the particle separator.
