Abstract:

Gnaiger 1983 Springer POS

When gas A is dry air and mixed with an oxygen-free dry gas or gas mixture B (e.g., N2), then the pO2 in water equilibrated with this gas mixture is

pO2 = (pbpH2O,TsϕA×ϕo2, (1)

where pb is barometric pressure [kPa], pH2O,Ts is the saturation water vapor pressure at the temperature of the water sample, ΦA is the volume fraction of gas A in the gas mixture leaving the gas mixing pump,

ϕA=pA/pb and 1−ϕA=pB/pb, (2)

ϕo2 is the volume fraction of oxygen in dry air which can be taken as constant ϕo2=0.20946.
