<p>A sampler containing a sample material (20) appllied to a substrate (30) with a cover (60) over the sample material. Sample material is deposited on the substrate by spray depositing the sample material on the substrate, which causes the sample material particles to lie in a substantially flat orientation. To enable the spraying of a material, a slurry is formed by mixing the sample material with a suitable carrier. The carrier then evaporates, leaving the sample material on the substrate.</p> |
