New Perspectives and Technology in Pyrolysis GC-MS for Forensic and Polymer Analysis:  How Smart-Ramped Pyrolysis Leads to Improved Data

Separation Science, in collaboration with GERSTEL, Inc, offers an on-demand webinar introducing new perspectives and technology in pyrolysis GC-MS for forensic and polymer analysis and describing how changes in pyrolyzer design lead to improved data. 

Duration: Approximately 50 minutes

Presenter
Kurt Thaxton
(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.

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 introductory webinar describes the hardware advances in more detail and provides examples of improvement in data quality, using samples drawn from forensic and polymer application areas. Follow-up webinars then approach each of these areas in detail.

By viewing this on-demand 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.
