| Abstract: | Abstract The standard technique of vapor phase osmometry has been modified to permit easier measurements on compounds with high vapor pressures (up to at least 5 torr). Wicks are used to create a continuous flow of Liquids onto the thermistors, thereby creating a steady-state concentration in the solvent-saturated atmosphere. Measurements with both aqueous and nonaqueous solvents are possible. In addition, the steady-state method applied to nonvolatile solutes was easier, faster, and more reproducible than the drop method. |
