Quantitative analysis of fatty acid methyl esters by capillary gas chromatography with flame-ionization detection: quadrupole and sector mass spectrometer.

The response of a flame-ionization detector and of two mass detectors, viz. a quadrupole mass spectrometer and a sector mass spectrometer, is described. A relationship between the amount of a fatty acid methyl ester and the relative response in the three detectors was found. The detectors were compared and their possible use for biological samples was discussed.
