A novel technique for the measurement of gas solubility and gas
content in liquids and suspensions is described. Saturation of the
liquid and subsequent extraction of test gas both took place in a
specially modified gas-tight syringe. Test gas was extracted from the
saturated liquid by bubbling an inert carrier gas through the liquid
('sparging'). All gas exiting the apparatus was directed towards a
mass spectrometer which thereby measured the volume of extracted test
gas in the presence of the carrier. The technique was used to measure
the solubilities of nitrogen, oxygen, carbon monoxide, carbon dioxide
and nitrous oxide in olive oil at 370C. The Bunsen solubility
coefficients so obtained are in good agreement with those obtained by
classical techniques.
