Original Measurements
Van Slyke, D. D.; J. Biol. Chem. 1939, 130, 545-54.
Variables:
Ambient temperature: 295.95 - 298.65 K
Pressure: 101.325 kPa
Prepared by:
Method/Apparatus/Procedure:
Measurements were made in a Van Slyke/Neill apparatus.1,2 In this kind of apparatus the equilibration and analysis were done in the same chamber. Shaking was done during saturation and degassing. Once equilibration was achieved the undissolved gas was removed and the solution analyzed for absorbed gases manometrically in a known volume.
Source and Purity of Materials:
- 99.9%.
- Not specified. Degassed.
Estimated Errors:
Ambient temperature: Not stated.
