MOSH/MOAH Sample Preparation Solutions
MOSH/MOAH Determination
Mineral oil hydrocarbons, comprising MOSH (Mineral Oil Saturated Hydrocarbons) and MOAH (Mineral Oil Aromatic Hydrocarbons), are compounds that enter the product life cycle at various stages of production. Sources of contamination include the environment, plant protection agents, machine oils, additives, and food packaging.
