Chapter 6 The Utility of Pyrolysis Studies

Abstract

This chapter discusses the utility of pyrolysis studies. Analytical pyrolysis has a number of characteristics that can make it a very powerful investigative tool. The technique usually requires a small amount of sample and can be set with very low limits of detection for a number of analytes. Analytical pyrolysis, typically having a GC/MS as an analytical instrument (Py-GC/MS), can provide both qualitative and quantitative information regarding pyrolysates. One common purpose for this technique is to determine the nature of the material that was pyrolyzed. Analytical pyrolysis applied to non-polymeric materials remains a very useful technique for the understanding of pyrolysate composition applied to compounds generated in human activities such as waste incineration, burning of specific fuels, cigarette smoking, and even burning of food during cooking. The chapter describes the use of pyrolysis in organic synthesis. Analytical pyrolysis is a valuable forensic tool as proven by its common use in forensic laboratories. The chapter discusses the various applications of pyrolysis in forensic science to problems related to illicit drugs and to the analysis of traces of lipids and fire debris.
