Foodstuffs are frequently found to contain undesired mineral oil residues, which originate in many cases from the packaging materials. A migration of hydrocarbons into the foodstuffs can occur in particular through the use of printing inks derived from mineral oils. Additionally, lubricants during food processing, wax coatings directly applied to the food, environmental pollution, jute bags, etc. can be sources for contamination.
The LC-GC System MOSH/MOAH is specifically designed for the sensitive and fast detection of mineral oil contaminations. Over the last years, this system has proven its performance in several routine environments in Europe. Due to the LC-GC Interface, a development of Axel Semrau, various LC and GC brands can be coupled. The method is comprehensively published and proven. Also EFSA published in the EFSA Journal 2012 : "Currently, the most effective methods for analysis of MOSH and MOAH in food and feed comprise extraction followend by pre-separation liquid chromatography (HPLC) online coupled to GC with flame ionization detection (FID)."*
Special advantages of the LC-GC-System MOSH/MOAH:
Beside the analysis of MOSH and MOAH in food, cosmetics or packaging, LC-GC coupled systems can be used for the analysis of PAHs, sterols and other analytes.
