Vapor space characterization of waste tank 241-C-105: Results from samples collected on 2/16/94
This report describes results of the analyses of tank-headspace samples taken from the Hanford waste Tank 241-C-105 (referred to as Tank C-105). Pacific Northwest Laboratory (PNL) contracted with Westinghouse Hanford Company (WHC) to provide sampling devices and to analyze inorganic and organic analytes collected from the tank headspace. For organic analyses, six SUMMA{trademark} canisters were delivered to WHC on COC 0061 11 on 2/14/94. At the request of WHC, an additional six SUMMA{trademark} canisters were supplied on COC 005127 on 2/16/94. Samples were collected by WHC from the headspace of Tank C-105 through the VSS on 2/16/94, but only three SUMMA{sup {trademark}} canisters were returned to PNL using COC 0061 11 on 2/18/94. The canisters were stored in the 326/23B laboratory at ambient (25{degrees}C) temperature until the time of the analysis. Analyses described in this report were performed at PNL in the 300 area of the Hanford Reservation. Analytical methods that were used are described in the text. In summary, sorbent traps for inorganic analyses containing sample materials were either weighed (for water analysis) or desorbed with the appropriate aqueous solutions. The aqueous extracts were analyzed either by selective electrode or by ion chromatography (IC). Organic analyses were performed using cryogenic preconcentration followed by gas chromatography/mass spectrometry (GC/MS).
