摘要：
A process challenge device includes a controllable response produced by using a filter material, configured such that a sterilant gas must pass through the filter material to reach the biological indicator (BI). The filter material provides a controllably absorptive barrier, where the absorption of the sterilant is via chemical reaction, through which the sterilant gas must pass to reach the BI.
