Instrumental background oxygen flux, J°O2 [MiPNet14.06], in a respirometer is due to oxygen consumption by the POS, and oxygen diffusion into or out of the aqueous medium in the O2k-chamber. It is measured in the range of experimental oxygen levels by a standardized instrumental background test, and is a property of the instrumental system. Instrumental background correction eliminates errors by systemic flux compensation, automatically performed by DatLab.
