Using a summa canister brings an important danger when useful for air sample selection and laboratory screening. The largest chance one particular encounters when employing summa canisters may be the probable with the Nickel Chromium Oxide interior coating to degrade, As a result exposing the air sample to uncoated stainless steel. Uncoated stainless-steel (304) is about 70% iron, which happens to be a hugely reactive and catalytic ingredient, and might advertise chemical reactions bringing about the loss of target compounds.
