Whitepaper: Mineral oil residues in food: Part 4, removing natural occurring alkanes

The determination of MOSH and MOAH in food can be done by an automated LC-GC-FID system for routine analysis.
Unfortunately, some food material like rice or chocolate contain natural occurring (odd numbered) alkanes in range of C23 – C33 which can interfere and heavily disturb the analysis of the MOSH fraction. These interferences can be removed by flash chromatography on aluminium oxide columns.
