Popis: An on-line SFE-SFC system was used to extract and chromatograph a synthetic prostaglandin from hydroxypropyl methylcellulose (HPMC), which is a widely used material in controlled-release drug formulations. The only sample preparation for the on-line SFE-SFC analysis of the dispersion was weighing the sample into the extraction vessel insert. The extraction efficiency for a four-minute extraction was approximately 65%.
