Versaperm Vapour Permeability measurement

Gas Chromatography Sensors

Gas chromatography involves vapourising a sample and injecting it onto the head of the chromatographic column.  A flow of an inert gas (such as nitrogen, helium, argon, or carbon dioxide) carries the sample through the column which contains a stationary liquid phase which is adsorbed onto the surface of an inert solid. An extremely wide variety of gas chromatography detectors can be used depending on the specific case. Non-selective detectors respond to all compounds (except the carrier) and selective detectors respond to individual chemicals or ranges of physical or chemical characteristics.  

At Versaperm we are not tied to any specific sensor types or manufacturer and so we can always select exactly the right sensor for an application. Versaperm is a world technology leader in the measurement of gas permeability. We offer not only instruments but also comprehensive testing and consultancy services.
