Sample Chamber

During osmolality measurement by the vapor pressure method, exposure of the blood sample to air lowers the blood CO2 content and hence osmolality. A modification of the sample holder of a vapor pressure osmometer is described allowing exposure of the blood sample to a gas mixture with known concentration of CO2 and O2 while inside the closed sample chamber. This restores its CO2 content and hence osmolality. Data are presented comparing the unmodified and modified vapor pressure method with the freezing point depression method. A table was prepared for further correction of osmolality in case the blood's PCO2 differs from that of the gas mixture.

Order Of Magnitude

Addition of a macromolecule to a solution will give rise to a large excluded volume for the centers of the solute molecules. This will cause an apparent increase in solute concentration which is of the same order of magnitude as that associated with the nonsolvent volumes reported in the literature. A critical examination of one of the procedures used for the determination of nonsolvent water—the vapor pressure method of Hill—is given, and it is concluded that, with the use of this method, it is impossible to detect any significant nonsolvent water surrounding bovine albumin for either sugars or polyols. Generally, data reported in the literature for the nonsolvent water of proteins or other macromolecules will be too high unless they are corrected for the excluded volume.
