Abstract

Various embodiments of the present invention are directed towards a system and method relating to depositing vapor in a sample. For example, a device includes a vapor source chamber configured to contain a vapor source material to generate vapor. An activation chamber is configured to contain a sample. The activation chamber is in fluid communication with the vapor source chamber to receive the vapor. A permeable separator divides the vapor source chamber and the activation chamber, and isolates the sample in the activation chamber while allowing vapor to pass between the vapor source chamber and the activation chamber. The device is sealable and configured to apply vacuum to the vapor and sample, to cause deposition of the vapor into the pumice stone samples.
