摘要
本文采用气相色谱法测定聚氨酯涂料中的游离甲苯二异氰酸酯（ＴＤＩ）。样品经处理后直接进样，用氢火焰离子化检测器（ＦＩＤ）检测，以内标法定量，简便易行，为该组分的测定，尤其是进行多批样品的测定提供了一种可选择的方法。
AbstractA new analytical method has been developed to deter-mine the residual TDI in polyurethane coating by use ofchromatagraphy. Sample is injected directly after treat-ment . FID( Flame Ionization Detector) is used . Quantita-tive analysis is carried out using internal calibration. Theresults is treated by microprocessor. This method fea-tures easy operation, fast and accurate, and provides abetter choice for deterrnination of residual TDI, especial-ly in a number of samples.
