Abstract
Multiphase headspace equilibration with gas chromatographic analysis was used for the simultaneous analysis of CH4, and N2 in Lake Erie sediment pore water, with total CO2 concentrations determined on a separate duplicate sediment sample. The minimum detectable concentrations of Ar, N2, CO2, and CH4 in a Lake Erie sediment were 1.55, 0.96, 2.50, and 1.01 ml/L, respectively, using a thermal conductivity detector. Precision of the dissolved gas analysis ranged from ±0.24 to ±0.41 ml/L.Keywords
