Abstract

Fatty acid is present in samples like butter, margarine and peanut butter. Fatty acids are not sufficient volatile in GC analysis. In addition, acids is very relative, reactive and are too polar to be well separated by gas chromatography. Direct GC analysis of acids tends to cause peak tailing due to absorption and no specific interaction with the column. Derivation is the process chemically modifying a compound to new compound has properties that are suitable to GC analysis. This experiment introduces a derivatization procedure usually used for fat analysis in which non volatile fatty acids are chemically converted to the corresponding volatile methyl ester (FAME). Thus resulting volatile mixture that can be analyzed by gas chromatography.
