Undesirable mineral oil residues are found in numerous foods or food contact materials. The complexity of the analytes requires special sample preparation and analysis. The BEKOlut® HPLC columns have been specially developed for MOSH/MOAH analysis.

They are aluminum oxide columns (Alox columns), which are essential for the separation and purification of fractions in LC-GC-FID analysis. They prevent interference, improve selectivity and optimize analysis quality.
