Patent

CA 2149118

The present invention relates to a sampler for a volatile fluid material, which sampler comprises: a) a vapour barrier base layer (1) having applied directly to a selected area of a first face thereof a volatile fluid material (2); b) a vapour barrier cover layer (3) applied directly and without an intermediate layer over at least said selected area of the said first face of the base layer; c) a seal (4) between at least the periphery of said base an d cover layers whereby there is formed a vapour barrier enclosure containing said volatile material, said seal being separable whereby a user can separate at least part of said cover layer from said base layer so as to expose at least part of said first face of said base layer directly to the atmosphere and allow the fluid volatile material to be released and to replace said cover layer so as to prevent further release of said volatile material. The invention also relates to a method for making a sampler of the invention.

Dispositif d'échantillonnage d'une matière fluide volatile. Il comporte (a) une couche vaporifuge de base (1) dont une première face présente une zone choisie sur laquelle on applique directement une matière fluide volatile (2); (b) une couche vaporifuge de recouvrement (3) placée directement et sans interposition de couche intermédiaire sur au moins ladite zone choisie de ladite première face de la couche de base; et (c) un élément d'étanchéité (4) placé au moins entre les périphéries desdites couches de base et de recouvrement de manière à former une enceinte délimitée par les couches vaporifuges et destinée à contenir ladite matière volatile, ledit élément d'étanchéité étant amovible de telle sorte que l'utilisateur puisse séparer au moins une partie de ladite couche de recouvrement de ladite couche de base afin d'exposer directement à l'atmosphère au moins une partie de ladite première face de la couche de base, pour permettre à la matière fluide volatile de se dégager, et de remettre en place ladite couche de recouvrement pour empêcher tout dégagement supplémentaire de ladite matière volatile. On a également prévu un procédé de fabrication d'un dispositif d'échantillonnage du type précité.
