Abstract: An aliquot (0.500 g) of solvent-based food contact coating sample was taken, and 5 mL of ethyl acetate was added. After ultrasound for 15 min, 20 mL of methanol was added, and the mixture was centrifuged for 10 min. An aliquot (0.500 g) of water-based food contact coating sample was taken, and 25 mL of methanol was added. The mixture was vortexed for 1 min, extracted by ultrasound for 15 min, and centrifuged for 10 min. The supernatant obtained was passed through an 0.22 μm organic filter membrane, and the filtrate was analyzed by high performance liquid chromatography. Using Acclaim^TM 120 C₁₈ chromatographic column as stationary phase, and the mixed solution composed of acetonitrile and 0.05% (volume fraction) aqueous ammonia solution at a volume ratio of 1∶9 as mobile phase, 3 imidazole compounds were separated by isocratic elution at a flow rate of 1.0 mL·min⁻¹. Determination was made at detection wavelengths of 211 nm (2-methylimidazole and 4-methylimidazole) and 227 nm (1-vinylimidazole). It was shown that linear relationships between values of the mass concentrations and peak areas of 3 imidazole compounds were kept in definite ranges, with lower limits of determination (10S/N) in the range of 5.0-20.0 mg·kg⁻¹. Test for recovery was made according to the standard addition method, giving recoveries in the range of 92.5%-108%, and RSDs (n=6) of the determined values were not more than 2.5%.
