Method/Apparatus/Procedure:

The Van Slyke-Neill manometric method which is based on the desorption of gases from blood in a partial vacuum was used. A small volume of solvent is saturated with gas by alternately bubbling the gas through the solvent and shaking the saturator at constant temperature and atmospheric pressure. A small, carefully measured volume of saturated solution is drawn into a 50 mL burette by lowering the mercury level in it. A partial vacuum is produced releasing most of the gas. The pressure, volume and temperature are measured. Corrections are made for the solvent vapor pressure (assumed to be as for water) and for the residual gas solubility in the solvent at the low pressure. Details in [1].
