Determination of Migration of 11 Organotin Compounds in Food Contact Materials by GCMS

Abstract:

The determination of the migration of 11 organotin compounds in food contact materials by GC-MS was established. The gastric acid was simulated with 0.07 mol/L hydrochloric acid solution, and the sample was soaked and extracted, and then derivatized with sodium tetraethylborate, extracted with n-hexane liquid solution, detected by GC-MS, and quantified by internal standard method. The linear range of the method is 5~600 μg/L, the correlation coefficient is greater than 0.997, and the method detection limit is 0.014 mg/kg. The recoveries of the three concentration levels ranged from 83.6% to 105.6% with a relative standard deviation of less than 11.4%. The method is simple and sensitive, and can be used for detecting the migration of organotin compounds in food contact materials.
