Recovery of volatile fatty acids from biological materials for direct analysis by gas chromatography.
A simple and efficient methodology for preparing aqueous extracts of volatile fatty acids from biological materials, for direct analysis by gas chromatography is described. Peak areas and responses relative to n-butyric acid were used to calculate concentrations of the individual acids. An example is given for analysis of the volatile fatty acids found in the blood of the lugworm Aerinocola marina.
