    Abstract - (Show below) - (Hide below)

    ISO/TS 21033:2011 specifies an inductively coupled plasma optical emission spectroscopic (ICP-OES) method for the determination of trace element content in oils. Depending on the dilution solvent used, most types of vegetable oils can be analysed (crude, degummed, refined, bleached, deodorized and hardened oils) and nearly all types of lecithins and phosphatides.

    This procedure is only suitable when the elements are present in a solubilized form. Fine particles, such as bleaching earth, metal particles and rust, can result in poor recovery of the trace elements present as nebulization and atomization problems affect the ICP-OES analysis.
