Title (EN) DETECTION SYSTEMS
(FR) SYSTÈMES DE DÉTECTION
Abstract:
(EN) An IMS system or the like has dopant contained in a way such that it is only released when needed. The dopant could be contained in a device (50) similar to an ink-jet printer and released as droplets (55) when required. Alternatively, the dopant could be trapped in material (156) of a molecular sieve (150) in such a way that it is not normally released into air flowing through the sieve but can be released by energising a heater (157) in the sieve.
(FR) L'invention concerne un système IMS ou autre qui comporte un dopant contenu de manière telle qu'il n'est libéré que lorsque nécessaire. Le dopant pourrait être contenu dans un dispositif (50) semblable à une imprimante à jet d'encre et libéré sous forme de gouttelettes (55) lorsque cela est requis. En variante, le dopant pourrait être piégé dans un matériau (156) d'un crible moléculaire (150) de manière telle qui ne soit pas libéré normalement dans l'air circulant au travers du crible mais qu'il puisse être libéré en alimentant un dispositif de chauffage (157) dans le crible.
