Development of Extraction and Separation Monitoring in Situ with On-line SFE·SFC/FTIR System

On-line SFE·SFC/FTIR with a high pressure flow cell withstanding pressures as high as 50 MPa was built up to make an in situ observation at supercritical state. The extraction and separation efficiency determined by this system was correlated with a parameter derived from solubility parameter concept.
