This method is suitable for the semi-quantitative analysis of oils, fats and oil/fat-related samples (deodistillates). Screening of oils, fats and oil/fat-related samples to obtain main (e.g. TAGs) and minor component (e.g. sterols, sterol esters, tocopherols, squalene, wax esters, fatty alcohols, and glycerol) information in one single analysis. For a truly quantitative analysis of pre-identified compound classes specific methods are more appropriate. Beside the (semi-)quantitative determination of the oil/fat composition mentioned above, the method can also be used as a useful qualitative screening tool for the relative comparison of sample compositions.
