Supercritical Fluids Phase Monitor

Supercritical Fluid Technologies has introduced a new Data Acquisition Package (DAP) as an option for the SFT Phase Monitor II instrument. The DAP provides real time image and data capture directly to a PC computer. The video image, along with the temperature and pressure data, is displayed on the PC monitor and may be archived directly to the hard drive. In addition, the current date and time are recorded and the user has the ability to enter a short text comment. To capture the video signal, the package includes a PXI (frame grabber) card, which needs to be installed into the user’s PC running Windows 2000, NT, XP, or Me. The software is based on LabView. All cables and connectors required to complete the installation are provided. The user is responsible for providing a suitable PC computer with Windows OS. The SFT Phase Monitor II is a powerful analytical tool for determining the solubility of various compounds and mixtures of compounds in subcritical and supercritical fluids. It provides direct, visual observation of materials under conditions that may be controlled precisely by the researcher. Experiments may be performed in liquid or supercritical carbon dioxide or in other compressed gases. Additionally, the effect of co-solvents on the solubility of compounds of interest in supercritical carbon dioxide can be investigated with this instrument. It allows the end user to view the dissolution, precipitation and crystallisation of compounds over a wide range of pressures and temperatures. Experiments can be done from a few hundred psi to 10,000 psi and from ambient temperature to 150ºC.
