中文摘要:
      采用裂解气相色谱/质谱联用（Py-GC/MS）仪分析RT培司（对氨基二苯胺）所含的杂质。结果表明：将RT培司和疑似杂质的导热油样品直接进样，通过GC谱峰的保留时间和MS谱的特征离子推断RT培司样品中的杂质为导热油。RT培司生产过程应避免此类物质的污染，以提高产品纯度。
英文摘要:
      The impurity in the RT base（p-aminodiphenylamine）was analyzed by using pyrolysis-gas chromatography/mass spectrometry（Py-GC/MS）method.The RT base and suspected impurity，heat conducting oil，were tested by direct sampling，respectively.The retention times indicated in GC peaks and characteristic ions in MS spectral showed that the impurity in RT base was heat conducting oil.The contamination of oil in RT base should be avoided in the production process in order to improve product purity.
