Analysis of a Layered Paint Sample using Pyrotomy

Summary

Samples comprised of multiple layers, such as laminated or coated papers, painted polymers, packaging and multilayered paint sytems may be applied to the platinum filament of a Pyroprobe and analyzed by applying short bursts of heat to work sequentially through the layers. This technique, called Pyrotomy, is also useful in determining surface contamination and the presence of additives on the outside of the polymer, such as mold-release compounds. The sample is heated for a second or less, then cooled to prevent further degradation while the products are analyzed by the GC/MS.
