| Abstract: | Systematic performance testing activities for supercritical fluid extractors consistent with the implementation of quality systems in analytical laboratories are proposed. In this context, supercritical fluid extraction (SFE) is used for the automatic processing of complex samples. Ensuring reproducible operation of SFE equipment is crucial with a view to obtaining traceable results. To this end, an assessment protocol including recommended preventive and corrective actions, and complementary internal quality control activities, was developed with a view to facilitating the use of SFE equipment by routine analytical laboratories. |
