For precise analysis of MOAH (Mineral Oil Aromatic Hydrocarbons) and MOSH (Mineral Oil Saturated Hydrocarbons) in palm oil, the gold-standard technique is online LC-GC-FID. This method efficiently separates MOSH and MOAH fractions and offers high sensitivity, accuracy, and compliance with international regulations. For more detailed characterization, LC-GC-MS or comprehensive two-dimensional GC (GC×GC-TOF-MS) can be employed.
