MOSH/MOAH Analyser

The GERSTEL-MOSH/MOAH Sample Prep Solution performs fully automated sample preparation and sample introduction for efficient determination of mineral oil residues in extracts of food, feed, body care products and packaging. The system is based on an online-coupled HPLC-GC/FID system using the GERSTEL MultiPurpose Sampler (MPS) for automated sample preparation and introduction.In the initial LC step, mineral oil residue is separated into two fractions: Mineral oil saturated hydrocarbons (MOSH) and mineral oil aromatic hydrocarbons (MOAH). These fractions are subsequently transferred to two separate GC columns for individual analysis in a combined dual channel GC system.
