C -8 H Ta-Wei and Hiromatsu-san, Based on your voice mail and latest note, I may have provided un-needed information to Hiromatsu-san as I w as responding with aqueous samples (i.e., groundwater or surface water) in mind. Certainly, as far as I know, w e d on 't apply the same analytical method for air sampling. I am going to proceed with forwarding our program QAPP to Hiromatsu-san in case he does want to review it as it provides our latest protocois/methodologies for C-8 sampling, including some that may apply to air sam pling.
