This method is actually used in preserving fingerprint, it hardens the fingerprint in place for later lifting. These are meant to remove vapors only as they are drawn over the filter media, typically charcoal and other solvent/acid/amine specific media. If the CA chamber is used for successive batches of evidence immediately upon removing items from a prior cycle, the heat source will still be warm and the time of exposure may have to be changed to prevent over-fuming in the subsequent cycles.
