标准简介：This Technical Specification specifies an inductively coupled plasma optical emission spectroscopic (ICPOES)
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.
NOTE The only suitable non-ashing direct method for samples containing fine particles is graphite furnace atomic
absorption spectrometry.
