AOCS Reference Mixes Available from Sigma-Aldrich

Reporter US Volume 26.4

The American Oil Chemists’ Society (AOCS) found certain Fatty Acid Methyl Ester (FAME) mixes to be useful as reference standards when performing quantitative analyses of animal and vegetable oils. The compositions of these reference mixes are cited in AOCS Method Ce 1-62.

Through its Supelco brand, Sigma-Aldrich is able to offer quantitative mixes conforming to the AOCS method requirements. The composition of each mix is similar to the fatty acid distribution of certain oils (see Table 1) and is carefully prepared by weight percent. The composition is then verified by gas chromatography using an independently prepared reference standard. A certificate of analysis is provided with each mix.
