| Abstract: | Supercritical fluid extraction (SFE) is a new separation method, which is rapidly developed recently. This paper describes a procedure for the supercritical fluid extraction of trace-level n-alkanes adsorbed on A12O3 with self-made apparatus and optimized operation conditions. In addition, orange peel and ginger were extracted and analyzed. The results demonstrate the simple operation, high efficiency, high level automation and reliability of this apparatus. It is a very useful technique for the extraction of trace-level organic compounds from a complex matrix. |
