Stability of extractable organic constituents in stored samples of gasification condensates inferred from comparisons of GC/MS total ion chromatograms
Samples of water and recycle oil were collected from the prequench tower of the gasifier crude-gas quench system of the HYGAS pilot plant. The samples were stored at refrigerator temperature (2-4/sup 0/C) for 60 days and at incubator temperature (37/sup 0/C) for 7 days. A dried oil sample and neutral, acid, base, and composite extracts were prepared at days 0, 29, and 60 for the refrigerated samples and at day 7 for the incubated sample. The extracts and dried oil were analyzed by capillary column gas chromatography/mass spectrometry on a 50-m OV-101 column. Minor differences in comparative total ion chromatogram traces can be attributed to variations in the concentrations of extraneous plasticizers or to slight differences in column resolution or sample extraction. No significant changes were apparent in comparative chromatogram traces for the refrigerated and incubated sample extracts and the dried oil. Within the limitations of this study, no degradation of organic components was found in the samples refrigerated for 60 days or in the sample stored at incubator temperature for 7 days. Argonne National Laboratory procedures for check-in, coding, and transfer of samples are also described.
