“…Galipo and co-workers were able to follow the progress of polymerization of a polyimide (Ciba-Geigy Matrimid 5292) by identifying characteristic pyrolates of both the reactants and the products. More information on the pyrolysis GC of coating materials is in the recent review by Haken …”

“…More information on the pyrolysis GC of coating materials is in the recent review by Haken. 39 Controlling the heat delivered to a pyrolysis mass spectrometry experiment can also create higher mass pyrolates. These higher mass pyrolates can then be analyzed by techniques such as MALDI or ESI (both MALDI and ESI will be discussed below).…”
Laboratories. Scott enjoys technical problem-solving using MALDI, gel permeation chromatography, and time-of-flight secondary-ion mass spectrometry. Away from work, Scott is very happy with his wife of 15 years, Helen, and their young son, Brian.

“…To date, no application of laser Py-GC/MS has been recorded for the characterization of microplastics, the use of laser having only been described in the context of the analysis of PS by matrix-assisted laser desorption ionization-time of flight (MALDI-TOF) (Schirinzi et al 2019;Lin et al 2020). Haken (1999) presents two key parameters to be addressed to perform reproducible analysis with pyrolysis coupled to gas chromatography when studying tiny particle with a mass below 1 mg, which is the case for almost a majority of MP.…”
By now the polymeric nature of microparticles has to be demonstrated before their classification as microplastics. Pyrolysis coupled to gas chromatography and mass spectrometry (Py-GC/MS) has been used for years to characterize polymers. Thanks to three distinct steps, destructuring, separation, and identification, this chapter explains how this technique allows the analyst to ascertain the polymeric
“…Pyrolysis is a well-known and successful method used either analytically or to recover monomers from waste polymers. For the last 50 years, many groups of materials have been analyzed by classic pyrolysis and variations thereof 4 . Pyrolysis methods are typically either on-line (where decomposition and analysis are conducted in one device) or off-line (decomposition and analysis proceed using separate systems).…”
Section: Pyrolysis and Pyrolysis Gas Chromatogra-phy (Py-gc) As Analymentioning
The general aim of this article is to review the state of knowledge on pressure-sensitive adhesives (PSAs) and pyrolysis. Recent research data in the field of pyrolysis gas-chromatography (Py-GC) analysis of acrylic PSAs are presented. First, PSA characteristics and applications, pyrolysis (including Py-GC) as an analytical method, and system solutions, are described. The latest scientific achievements in the analysis of thermal degradation products of acrylic PSAs are then presented.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
