A gas chromatography method, with an OV-101 capillary column, was established for quantifying the minor phenol and DPC in the MPC sample. The quantitative result showed the mass concentrations of phenol and DPC were 2.04% and 1.59% respectively.

• 在常规气相色谱仪中采用OV-101毛细管色谱柱；以苯甲酸乙酯为内标物；对自制MPC标准品中的微量苯酚和DPC进行了定量分析；苯酚和DPC 的质量浓度分别为2.；04%25和1
