Abstract: Supercritical fluid extraction is a new and “green”technique for extraction and separation with such advantages as high efficiency, high speed, and less pollution. This paper reviews the on-line detection techniques in supercritical fluid extraction, including supercritical fluid chromatography, gas chromatography, high-performance liquid chromatography, nuclear magnetic resonance, and near infrared spectrometry.
