    Abstract

    Two simple procedures for trapping volatile accelerant vapors are presented as alternatives to other techniques which utilize passive diffusion. These procedures take advantage of the simple diffusion of volatiles into the headspace of a closed container and trap the vapors onto charcoal which is either encased in a porous pouch or impregnated into a flexible membrane. Data demonstrating the abilities of these procedures to collect accelerant vapors with respect to changes in adsorption time, temperature, and sample concentration are presented.
