Saturated O2 concentration in Tris buffer?

I need to know the concentration of oxygen in air saturated 50mM Tris-HCl
pH7.6 buffer at 25C in order to interpret some oxygen electrode data I
have.  Does anyone have a value (preferably with reference) for this? I
think the effect of salts on solubilities at low concentrations may be
additive so I guess values for different concentrations could be scaled
to 50mM?
