Abstract

In this work, we developed supercritical fluid chromatographic methods for the samples which are difficult to analyze with conventional GC or HPLC. Long-chain Hydrocarbons, mink oils and soybean oils unsuitable for GC because of their low volatility or limited thermal stability were separated by SFC due to the high solvating properties of supercritical carbon dioxide fluids. In our research, a new method for the analysis of polar fatty acids and pesticides was developed. This method should be used to overcome problems with polar samples in SFC.
