Abstract: The gas chromatographic analysis technique can fast and accurate determine the plasticizer content in milk drinks. Refer to the SN/T 2037-2007 and GB/T 21911-2008 requirements, a specific analysis method is provided upon GC which is a self-developed product of the Shanghai Shangjiqunli Analytical Instrument Co., Ltd. Dimethyl phthalate(DMP), diethyl phthalate (DEP), dibutyl phthalate, n-dioctyl phthalate (DNOP) components in Milk Beverage were analyzed by this GC. The?relative?average?error?of retention time and peak area, 0.271% and 1.80%,respectively, the blank recycle ratio of the three components was above 60%.
