Abstract:

When gas A is dry air and mixed with an oxygen-free dry gas or gas mixture B (e.g., N₂), then the p_O₂ in water equilibrated with this gas mixture is

p_O₂ = (p_b−p_{H₂O,T_s})×ϕ_A×ϕ^∗_o₂, (1)

where p_b is barometric pressure [kPa], p_{H₂O,T_s is the saturation water vapor pressure at the temperature of the water sample, Φ_A is the volume fraction of gas A in the gas mixture leaving the gas mixing pump,}

ϕ_A=p_A/p_b and 1−ϕ_A=p_B/p_b, (2)

ϕ^∗_o₂ is the volume fraction of oxygen in dry air which can be taken as constant ϕ^∗_o₂=0.20946.
