文摘
- •
The gas trapping device method (GTD) offers a reliable alternative method to measure N2 flux from waters.
- •
GTD method was tested with the non-equilibrium diffusive error and compared with Membrane Inlet Mass Spectrometry method (MIMS).
- •
There were minor non-equilibrium diffusion errors for GTD, with the maximum error of 2.99% under highest gradient difference of N2 partial pressure.
- •
N2 fluxes obtained by GTD and MIMS methods were very similar under the same experimental condition.
