 Solubility of oxygen in organic solvents

Hi,
 I have been told that organic solvents such as hexane, heptane etc dissolve
far more oxygen than aqueous solutions.  I cannot find any specific
references in the literature to this and woiuld like to quantify the
difference in oxygen solubility between solvent and aqueous systems. The
Oxygen electrode is  fine for aqueous solutions (in fact solubility data for
aqueous systems is readily found in the literature) but I need a method for
solvents. Does anyone know of a reliable method for measuring dissolved
oxygen in solvents ?
many thanks
Paul

You can find data for oxygen solubility in lots of solvents in the
IUPAC Solubility Data Series, vol. 7, "Oxygen and Ozone," Pergamon
Press, Oxford, 1981.
