Tank 241-S-111 headspace gas and vapor characterization results for samples collected in March 1995

“…All inorganic gas and vapor tank samples, ambient air samples, and trip and field blanks were prepared and analyzed by PNL per PNL quality assurance impact level 2 procedures (Klinger et al 1995a). PNL analyses of SUMMATM canisters and sorbent traps for inorganic compounds were performed 5land 20 days, respectively, after sample collection (Ligotke 1995). Both SUMMAm canister, and sorbent trap analyses were within the maximum 60-day holding time allowed by the WHC quality assurance project plan (Keller 1994).…”

“…Nitrous oxide has been detected in other passively ventilated waste tanks at average concentrations as low as about 12 ppmv in tank TX-105 (Klinger et al 1995b), and as high as 878 ppmv in tank U-103 (Ligotke et al 1995). Under the proper conditions, nitrous oxide can serve as an oxidizer to support combustion.…”
