摘要

Previous work in this area of pyrolysis-gas chromatography-mass spectrometry 1-5 has shown that this technique is a powerful analytical tool suited for studying the complex composition of intractable materials, such as vulcanized elastomers. An interesting and particularly valuable application of the many pyrolysis techniques available is serial chromatopyrography-mass spectrometry (Ser-Py-GC-MS). This technique appears to be very applicable to separating residual vulcanizate formulation components from polymer composition without the need for complicates sample manipulation procedures. Instrumental techniques employing a combination of serial pyrolysis techniques, high resolution capillary gas chromatography, and mass spectrometry have been developed at the U.S. Army Materials technology Laboratory, in collaboration with the U.S. Tank-Automotive Command (TACOM), during the last several years. The technique is used as a means of accurately accessing and reconstructing formulations of vulcanized elastomers where few, if any, straightforward analytical procedures are available for this type of work. Applications of serial pyrolysis-gas chromatography-mass spectrometry, developed at the U.S. Army Materials Technology Laboratory, are used to determine the qualitative organic formulation and polymer composition of two proprietary experimental natural rubber formulations.
