Supercritical fluid chromatography (SFC) has been practiced for approximately 50 years. SFC on packed columns for both qualitative and quantitative purposes underwent a renaissance in interest at the beginning of the 1990s when limitations of capillary SFC became obvious and important progress in composition gradient techniques for mixed mobile phases was achieved. Even with these instrumental improvements, wide acceptance of the technology was not forthcoming because the perception was that highly polar analytes were not soluble in carbon dioxide and thus were not separable. It is now apparent that the use of additives dramatically extends the range of solute polarity amenable to SFC.

The high-throughput analysis of pesticides in raw agricultural commodities has been hindered by the slow and laborious sample preparation stages. Using traditional clean-up procedures, as many as 20 steps are required to get the sample in a convenient form for analysis, which typically limits sample throughput to eight samples per day. This study evaluates a new approach using a novel laboratory mill and pulverizer to extract various pesticide residues from different kinds of plant materials and to identify and quantitate the active ingredients by liquid chromatography–tandem mass spectrometry (LC–MS-MS). It shows that by automating the procedure, the number of clean-up steps can be reduced significantly, which increases sample throughput over traditional approaches.
