Abstract:
As recycled materials gain increasing importance in forming a sustainable global economy, the screening of non-intentionally added substances (NIAS) in post-consumer recycled (PCR) materials assumes a central role to ensure safety of recycled materials. Due to the large number of volatile and semi-volatile organic species in PCR, commonly used analytical techniques such as GC-MS often cannot provide sufficient resolving power and identification accuracy. In this talk, we will demonstrate the utility of GC×GC coupled with high-resolution mass spectrometry (HRMS) to efficiently separate and identify organic contaminants in complex post-consumer recycled (PCR) samples with each molecule tagged in an identification confidence system using mass pattern match scores, retention index matching, and high-resolution mass error. This talk can provide insight into the application of comprehensive GC-MS to complex samples of sustainability.
