RS ISO 21033: 2016
Animal and vegetable fats and oils — Determination of trace elements by inductively coupled plasma optical emission spectroscopy (ICP-OES)
Abstract

This International Standard specifies an inductively coupled plasma optical emission spectroscopic
method (ICP-OES) for the determination of the 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. Milk and milk
products (or fat coming from milk and milk products) are excluded from the scope of this International
Standard.
This method 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.
NOTE The only suitable non-ashing direct method for samples containing fine particles is graphite furnace
atomic absorption spectrometry
