Lipids, Fats and Oils
These methods of the American Oil Chemist Society (AOCS), Association of Official Analytical Chemists, International (AOAC), American Association of Cereal Chemists (AACC), and related peer-reviewed research journals, are specifically designed for the analysis of oilseed, fats, oils, foods/feeds, cereals, etc., where sample amounts are suitable for each test requested. Methods include standard wet chemistries, high-performance liquid chromatography (HPLC), gas-liquid chromatography (GLC) and mass spectrometry (MS).
Current academic or corporate price lists for analytical services are available by e-mail. Please refer to the sample submittal webpage for information pertaining the declaration of 'supplements' and reagent grade lipids, fats, etc., prior to analysis.
