-|abstract=For calibration of the polarographic oxygen sensor (POS) and for measurement of instrumental background oxygen consumption, only incubation medium but no biological sample is added into the Oxygraph-2k chamber, at experimental conditions. In a closed chamber under these conditions, ideally oxygen concentration remains constant. In practice, however, instrumental background effects are caused by back-diffusion into the oxygraph chamber at low oxygen pressure, oxygen diffusion out of the oxygraph chamber at elevated oxygen levels, and oxygen consumption by the polarographic oxygen sensor (POS). Instrumental background interferes with accurate measurement of respiratory oxygen flux, if background effects remain undefined. Determination of instrumental background constitutes an important standard operating procedure (SOP) in high-resolution respirometry (HRR) Instrumental background oxygen flux is (i) minimized in the OROBOROS Oxygraph-2k by instrumental design and selection of appropriate materials. In addition, (ii) instrumenal background is routinely tested, and (iii) background correction of oxygen flux is applied automatically by DatLab.
