ABSTRACT:
This invention relates to a method and device for continuously removing and concentrating specific molecules or substances from a gas stream and depositing such molecules or substances in a liquid film stream in a controlled and quantitative fashion. The device includes a hollow tetrafluoroethylene tube or a hollow tube having an inner surface coating of tetrafluoroethylene. The inner surface of the tube is etched by means of a chemical etching agent. An inlet/injector is attached to the outer circumference or inlet, circumferential face of the tube. The inlet/injector has liquid dispersion ports uniformly distributed around the circumference of the processor tube whereby a surfactant containing liquid may be uniformly dispersed from the inlet/injector onto the inner wall of the processor tube where it may flow, in a thin film manner, from the inlet of the tube to the outlet of the tube. The inlet/injector also has a gas injection port whereby a gas containing the molecules or substances sought to be removed and concentrated can simultaneously be injected into the top hollow portion of the tube. An outlet cap is attached to the outer circumference or outlet circumferential face of the tube. The outlet cap has a liquid collection well with a port or other means whereby the liquid flowing down the inner wall of the tube can be collected and transported to an analyzer. The outlet cap also has a gas port whereby the sample gas undergoing analysis can be removed from the tube and vented, treated or otherwise disposed of.
