Abstract
A method is described for the direct mass spectrometric analysis of the products of supercritical fluid extraction processes. A sample placed in an extraction cell is pressurized to supercritical conditions with a high pressure pump. The extracted products are continuously analyzed by direct fluid injection of a small sample (n-pentane-isopropanol mixture at 280°C and pressures of 10 to 100 atm.Keywords
