中文摘要:
      采用PEG毛细管柱,以1,2,4-三氯代苯作内标物,气相色谱法测定聚氨脂涂料中游离甲苯二异氰酸酯的含量.其线性范围0.1%~10%,变异系数为5.1%.
英文摘要:
      A method to determine residual isocyanate concentration in coating using PEG capillary gas chromatography has been established. The linear response range is 0.1%~10% and the variation coefficient is 5.1%. The results of sample analysis are satisfactory.
