How to sample air using a SUMMA Canister

[@_istudywater]

Great video! I have a vapor intrusion project going on now!

This is a fairly good video. Most regulators/restrictors don't do 1 hour sample though, is the 1 hour a "grab" sample? In which case, you could do it much faster instead of 1 hour. Most regulations are 8 hour and 24 hour aren't they? 8 hour TWA for commercial and 24 hour TWA for residential?

If you want a good amount of flow, it's hard to sample for 8 hours straight with 1 canister.
