Objective
The objective of this study is to highlight the benefits and limitations of two analytical techniques, FTIR and PYMS.
Analytical Strategy
FTIR is sensitive to any component at a concentration of roughly 5% or greater, thus the technique is generally applied for identification of the chemical composition of the polymer matrix but not the additives package or other minor sample components.
PYMS is intended for the analysis of polymer systems and is most useful for the ability to identify polymer and copolymer varieties in addition to many polymer additives (e.g. antioxidants and stabilizers). This powerful technique provides excellent resolution for identifying components in a complex mixture. For most polymer systems, PYMS offers more definitive identification and greater sensitivity than FTIR, down to the single digit ppm range for many compounds.
