A sampler is shown for a volatile fluid material. The fluid material is applied to a face of a base layer. A cover layer is applied directly over the face without an intermediate layer. A peripheral seal is formed between the base and cover layers. The seal is separable by a user to expose the face of the base layer directly to the atmosphere to allow the fluid volatile material to be released. The cover layer can be replaced to prevent further release of the volatile material. A method is also shown for making the sampler.

A generally planar sampler for a liquid volatile material, which sampler comprises: a. a planar substantially vapour proof barrier base layer having applied directly to a selected area of a first face thereof a fluid material containing a liquid volatile material; b. a planar substantially vapour proof barrier cover layer applied directly and without an intermediate layer over at least said selected area of said first face of the base layer; c. a seal between at least the periphery of said base and cover layers whereby there is formed a substantially vapour proof enclosure for 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 liquid volatile material to be released by volatilization from said base layer, said seal also being reformable upon replacement of said cover layer so as to prevent further release of said volatile material.
