Acquity UPLC Analysis of Edible Oils

This application note describes a 10-minute separation and identification method for analysis of edible oils with Waters^® ACQUITY UPLC^®/PDA system using low toxic solvents, acetonitrile and 2-propanol as the mobile phase. The UPLC/PDA method not only allows faster and more precise analysis of triglycerides to authenticate the edible oils but also detects oxidized and decomposed triglyceride, enabling simultaneous determination of oil purity.
