Validation against AOCS protocols of microwave-assisted sample preparation for FAME analysis
1 Sept 2026This application note evaluates microwave-assisted sample preparation methods for fatty acid methyl ester (FAME) analysis against established AOCS protocols across a range of food matrices. Learn how the ETHOS™ X microwave platform enables fat extraction, derivatization and FAME profiling with accuracy comparable to conventional AOCS methods while reducing analysis time, reagent consumption, and operator exposure to hazardous chemicals. Discover the performance of one-step and two-step microwave workflows for determining saturated, monounsaturated and polyunsaturated fatty acid profiles in food and feed applications.
