New perspectives and technology in pyrolysis GC-MS

by | Feb 21, 2019

Discover how changes in pyrolyzer design lead to improved data with examples using samples from forensic and polymer application areas.

Would you like to simplify method development for pyrolysis GC-MS? If so, this webinar outlines the benefits of a filament-based pyrolyzer that offers the advantages of both platinum filament and furnace-based designs simplifying method development and increasing the number of compounds produced by the process. 

This webinar is now available to view on-demand.


What does it cover?

Pyrolysis-GC-MS has evolved over a fifty year period into one of the most useful tools for polymer and forensic samples. For many years, pyrolyzers based on platinum filaments were the dominant technology due to their flexibility, but then furnace-based designs also became popular due to their stability. In each case trade-offs were made. A third way forward was needed.

A new filament-based pyrolyzer was developed that provided the benefits of both: not only accurate on-demand calibration, measurement, and stability of pyrolysis temperatures but also the flexibility to rapidly ramp pyrolysis temperatures and non-selectively trap the pyrolysates. These features, along with the elimination of valves and transfer lines, simplify method development and increase the number of compounds produced by the process.

This webinar describes the hardware advances in more detail and provide examples of improvement in data quality, using samples drawn from forensic and polymer application areas.

By viewing this presentation you will learn:

  • How recent technology can provide more accurate and reproducible analytical results.
  • How the advanced design eliminates active sites and sample carryover compared with other systems.
  • How Smart-Ramped Pyrolysis can reduce method development time, increase the number of observable compounds, and reduce the amount of sample needed for optimal data.

(GERSTEL International Product Manager, Pyrolysis and Thermal Desorption)

Kurt Thaxton got his first taste of polymer analysis straight from graduate school, pyrolyzing paper and coating samples at International Paper. Having determined most pyrolysis instruments were less than optimal, he decided there must be a better way. Seven years later Kurt moved on and became involved in developing new instrumentation, as a mass spectrometry specialist, business director, and now as International Product Manager for Pyrolysis and Thermal Desorption at GERSTEL. His main focus is in instrument design and development of standard methods at SAE, ASTM and ISO.
