Thermal desorption gas chromatography-mass spectrometry for investigating the thermal degradation of polyurethanes

Abstract

Thermo-Desorption Gas Chromatography-Mass Spectrometry (TD-GC-MS) was used to investigate the thermal degradation of two different polyurethanes (PU). PU samples were heated at different heating rates and the desorbed products were...

Self-evolutionary recycling of flame-retardant polyurethane foam enabled by controllable catalytic cleavage

“…S15, ESI†). 70 Both FTIR and NMR analyses revealed a significant reduction in the content of oligomerized contaminants in the polyols recovered from PU/CCs when subjected to the milder degradation conditions of 180 °C for 270 minutes. When examining the low mass region (0–1600 Da) of the MALDI spectrum, we observed a gradual decrease in the low-molecular-weight residues of PU hard segments in recycled polyols, primarily composed of ethylene glycol-terminated MDI and its derivatives.…”

A Review of Weathering Studies in Plastics and Biocomposites—Effects on Mechanical Properties and Emissions of Volatile Organic Compounds (VOCs)

“…Thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS) is a widely used analytical method for analysing the release of volatile organic compounds (VOCs) during weathering of polymers. This method involves heating the polymer sample in a controlled environment to release VOCs, which are then analysed using GC-MS [ 93 ]. TD-GC-MS allows for the simultaneous analysis of a wide range of VOCs, including those that are difficult to detect using other techniques.…”

Diverse thermal desorption combined with self-aspirating corona discharge ionization for direct mass spectrometry analysis of complex samples

“…19 Specifically, atmospheric soft ionization techniques, including electrospray, plasma, or discharge methods, 20–22 are preferred in DSMS, while desorption can be accomplished by a variety of means, such as laser ablation, ultrasound, collision, or heating. 23–25 Moreover, these technologies can be flexibly combined to form diverse detection strategies for different samples.…”
