Abstract An HPLC procedure for determining sorbitol in bulk sorbitol is described. An Aminex HPX-87 column (Bio-Rad) is used with water as a mobile phase and with a refractive index detector to monitor column eluate. Sorbitol is separated from pentaerythritol, erythritol, ribitol, ethylene glycol, propylene glycol, arabitol, galactitol, mannitol, iditol, and other carbohydrates. The precision of the sorbitol determination, characterized by a 95% confidence interval, corresponds to ±1.22%.

The Lorentz–Lorenz coefficient for sulfur hexafluoride has been measured over the density range 0.1 g/cm3 to 1.3 g/cm3. The critical density has been measured and is 0.736 ± 0.001 g/cm3. Refractive index and density are both measured in the same experiment yielding values of the Lorentz–Lorenz coefficient accurate to 0.05% for densities near critical. The method utilizes a prism-shaped high pressure cell which can be removed from a temperature controlled holder and weighed on a precision balance. The cell is equipped with a needle valve which allows the high pressure gas to be bled out in steps. Refractive index is measured as a function of weight and hence density. Studies of sulfur hexafluoride indicate a small variation of less than 0.5% over the density range covered. A knowledge of the density dependence is necessary for interpretation and verification of the validity of recent experiments near the critical points of pure fluids.
