Abstract: A method for preparing a fragrance composition which comprises sampling from a plurality of sampling points, each containing a fragrance component, using a plurality of samplers, one sampler transferring an aliquot from one such sampling point to a mixing container, mixing the aliquots and testing the hedonic effect against a fragrance concept. A cleaning arrangement may also be provided where each sampler is cleaned after it has transferred an aliquot from the sampling point to the container before taking another aliquot from a second sampling point.

Abstract: A volatile substance dispenser including an inner open-top container for receiving and holding a heat source, such as a candle, and an outer open-top container for receiving and holding a gel containing a vaporizable or diffusable substance that passes from the gel into the surrounding atmosphere after exposure to the thermal energy from the lighted heat source, e.g. candle. The inner container can be glass, ceramic, earthenware or metal, preferably glass with a roughened outer surface.
