The quality and the quantity were done together. Under the optimum separation condition, the three monomers in water food simulants were separated well. The recovery varies from 90.2% to 108.5%, the RSD of result varies from 6.07% to 8.42%, and the detection limitation is all 0.01 mg⋅kg－1. The method is simple, rapid, sensitive and accurate. The method can meet the correlative requirements of the 2002/72/EC, 78/142/EEC and US FDA CFR 177.1020.
