The SFT Phase Monitor II is a powerful analytical tool for determining the solubility parameters of compounds and mixtures in subcritical and supercritical fluids. It provides direct, visual observation of materials under conditions precisely controlled by the researcher. Experiments can be performed in liquid or supercritical carbon dioxide and in other liquefied gases. Additionally, the effect of co-solvents on the solubility of compounds in supercritical carbon dioxide can be investigated with this instrument. It allows the end user to view dissolution, precipitation, and crystallization of compounds over a wide range of pressures and temperatures. Experiments may be performed from a few hundred psi to 10, 000 psi (68.9MPa) and from ambient temperature to 150 Celsius. The Phase Monitor II is extremely useful for determining the critical point of binary, tertiary, and complex mixtures. The changes in phase behavior as a function of temperature, pressure, and sample concentration can be investigated rapidly, saving time in the scale-up of supercritical fluid processes. The phase monitor can be utilized to determine the processing conditions in which each compound in a homologous mixture solubilizes andor precipitates. This data is useful for determining processing conditions for selective extraction, reaction, andor fractionation of compounds of interest. Additionally, supercritical "anti-solvent" applications are possible.
