Abstract:
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 = (pbβpH2O,Ts)ΓΟAΓΟβo2, (1)
where pb is barometric pressure [kPa], pH2O,Ts is the saturation water vapor pressure at the temperature of the water sample, Ξ¦A is the volume fraction of gas A in the gas mixture leaving the gas mixing pump,
ΟA=pA/pb and 1βΟA=pB/pb, (2)
Οβo2 is the volume fraction of oxygen in dry air which can be taken as constant Οβo2=0.20946.
