Hi All,
For those that have switched to PTFE/Teflon-based filters for air samples and
lapel filters:
We're now using Eichrom PTFE.
What effect has it had on your self-absorption/attenuation/transmission factors
for:
1. Air Samples?
2. Lapel Filters?
In the 2013 EPRI alpha guideline they mention the PNNL study (PNNL-SA-62011)
that recommends no self-absorption factor for PTFE/Teflon-based media.
Thoughts?
Thanks,
Rick
