Study design

Details on sampling:
Condensate water were obtained from a slagging fixed-bed gasifier at the Grand Forks Energy Technology Center (GFETC) of the U.S. Department of Energy, Grand Forks, ND. All handling and analyses of the samples were performed under nitrogen. After even a brief exposure to air, the solution
darkened and precipitates formed. A portion of each sample was adjusted to pH 2 with H2SO4 at the time of collection.
Samples were transported by air express promptly after they were obtained and were stored in the dark at 4°C. Measured values of pH for unacidified samples were about 8.5.
