- 7.1.1The erucic acid content of the sample, expressed in terms of its methyl ester as a percentage of the total fatty acid methyl esters prepared from the sample, is given by:
- 7.1.2If peak areas are obtained in percentages the values for EF and RF may be calculated as follows:
- 7.1.3The method of calculation (7.1.1) assumes that the level of tetracosanoic acid in the sample is negligible. If significant amounts of this acid are shown to be present the value for tetracosanoic acid (L2) obtained from the chromatogram of the fractions containing the remainder of the fatty acid methyl esters must be reduced to:
