摘要 分别建立PU革中N-甲基吡咯烷酮残留量的气-质联用法(GC-MS)和高效液相色谱-二极管阵列检测器(HPLC-PDA)检测法,并比较了2种方法在实际检测过程中的优缺点,2种方法均可满足生态纺织品标准(Oeko-Tex Standard 100)对NMP检测要求,但中等极性色谱柱的GC-MS法的灵敏度和色谱峰分离度均好于HPLC-PDA法。 Two methods for 1- methyl- 2- pyrrolidinone (NMP) analysis in the polyurethane leather were developed by gas chromatography with mass spectrometry detector (GC- MS ) and high performance liquid chromatography with photodiode array detector ( HPLC-PDA), respectively. The virtues and limitations of the above approaches were compared during the actual application. Both testing methods can meet the demand for determination of NMP residual in polyurethane leather according to Oeko-Tex Standard 100. The GC-MS on a column of medium polarity had higher sensitivity and better separating resolution for chromatographic peak of NMP with other peaks than HPLC-PDA.
