Abstract A GC-MS method for the high throughput determination of 20 phthalate esters in meat products is described
in this paper. Phthalate esters were purified online by gel permeation chromatography (GPC), separated on an Rtx-5 MS
chromatographic column using nitrogen as carrier gas, and monitored using a mass spectroscopic detector. The limit of
detection of the proposed method was 0.5 mg/kg. The average spike recovery rates were in the range of 95.68%－99.29%
with a relative standard deviation of 1.31%－3.32%. This method was repeatable, sensitive and effective for determining
phthalate esters in meat products.
