The Use of Supercritical Fluid Extraction as a Sample Preparation Technique for Soils


Using off-line supercritical fluid extraction (SFE), polynuclear aromatic hydrocarbons (PAHs) were extracted at different levels from various soil and sediment matrices. Based upon GC/MS measurements a number of SFE operational parameters including pressure, temperature and flow rate, were optimized to yield the highest efficiencies with the best precision.
