Effects of sample volume on the size of bacterial blanks
Following sparging with N2 gas, bacterial concentrates (2 mL) in 20 mL vials were injected with incremental volumes of DIW or NO3--deplete surface Sargasso seawater. Solutions included air-equilibrated DIW (for ≥ 1 day) and helium-sparged DIW (for 30 minutes), as well as air-equilibrated vs. helium-sparged seawater. N2O yields were estimated from peak areas recovered by mass spectrometric analysis, calibrated with standard additions.
