Discussion

In order to create an oxygen free environment, a vapor barrier film may be used. Then the sealed environment is purged with a non-oxygen gas, such as argon or nitrogen, and oxygen scavenger tablets are added to maintain the low oxygen concentrations (CAMEO). If oxygen levels are kept at or below 0.1%, all life stages of ten common museum insects can be killed in ten days (Daniel, et al., 1990).
