Analysis of trace volatile organic compounds (VOCs) and odor in post-consumer recycled resins by thermal desorption and GC×GC–TOF MS

With the global push towards a circular economy, there are renewed efforts to recycle plastics and to use post-consumer recycled (PCR) plastics, especially in food packaging. However, there are numerous challenges in providing high quality food packaging with PCRs because of volatile impurities, which originates from weathering, contamination, and thermal degradation.

This webinar shows how thermal desorption (TD) and comprehensive two-dimensional gas chromatography with time-of-flight mass spectrometry (TD-GC×GC-TOF MS) can provide detailed characterization of complex odor and volatiles profiles from PCR resins, as well as confident taste and odor analysis of the packaged products.

Key Learning Objectives:

  • Find out the challenges involved in the analysis of post-consumer recycled plastics
  • Learn how TD-GCxGC-TOF MS can improve detection of trace odorants
  • See how novel software workflows can uncover hidden differences between VOC profiles
  • Explore real world examples of taste and odor analysis applied to bottled beverages
Who Should Attend:
  • GC users who want to find out more about GCxGC
  • Polymer scientists who want to understand more about odors from recycled plastics
  • Food and aroma analysts who want to enhance their ability to analyze complex VOC profiles
