This document specifies the determination method of 2,2,4,4-tetramethyl-1,3-cyclobutanediol migration in plastic materials and products used in food contact.

This document is applicable to the determination of migration of 2,2,4,4-tetramethyl-1,3-cyclobutanediol in plastic materials and products used in food contact.



Haohan Chromatography (Shandong) Application Technology Development Co., Ltd. established an analytical method for the determination of the migration of 2,2,4,4-tetramethyl-1,3-cyclobutanediol in food contact materials and products by gas chromatography mass spectrometry (GC-MS). Methods The samples were soaked in food simulant 4% acetic acid and 95% ethanol. The water-based simulant (4% acetic acid) was extracted by acetonitrile, the oil simulant (95% ethanol) was evaporated to dryness by rotation, the volume was fixed by n-hexane, and PEG-20M (30 m × 0.25 mm,0.25 μ m) After the chromatographic column is separated, it is detected by gas chromatography-mass spectrometry and quantified by external standard method. Results The detection limit of this method was 0.005 mg/kg; The linearity is good in the range of 0.1~2.0 mg/L, r ^ 2=0.9991; When the spiking concentration is 0.1 mg/kg and 0.5 mg/kg, the recovery is 80.7%~93.7%, and the relative standard deviation (RSD) is 2.82%~6.22%. Conclusion The method is sensitive, rapid and accurate, and can be used to determine the migration of 2,2,4,4-tetramethyl-1,3-cyclobutanediol in food contact materials and products.
