ABSTRACT

Various correction factors have been proposed for quantitative analysis of fatty acid methyl ester mixtures by isothermal gas-liquid chromatography (GLC) employing thermal conductivity detectors in an effort to obtain more accurate values. These factors include multiplication of the area of each peak by the square root of the molecular weight of each component before calculating the percentage of each compound in the mixture or applying corrections for relative molar response for saturated esters and relative mass response for unsaturated esters. These proposed factors are not valid corrections for detector response but fortuitously are approximate compensations for lack of optimum operating conditions for each component. This is shown from the analysis of a number of standard fatty acid methyl ester mixtures by isothermal and programmed temperature GLC where the detector is maintained under identical conditions. Isothermal GLC requires different factors each time operating conditions are altered appreciably while proper temperature programming required little or no corrections depending on the particular mixture of methyl esters.
