Pyrolysis-Gas Chromatography/Mass Spectrometry of Polymeric Materials
نویسنده
چکیده
Structural analysis and the study of degradation properties are important in order to understand and improve performance characteristics of synthetic polymers and copolymers in many industrial applications. Polymers/copolymers cannot be analyzed in their normal state by traditional gas chromatography (GC) because of high molecular weight and lack of volatility. However, by heating these macromolecules to temperatures above 500 °C, they are pyrolyzed into many individual fragmentation substances, which can be then separated chromatographically and identified by mass spectrometry.

Development of a simple vent-free interface for capillary gas chromatography-mass spectrometry.
A novel and simple interface for capillary gas chromatography-mass spectrometry (GC-MS) was developed using a piece of deactivated stainless-steel tubing. This interface eliminated the need to vent the MS ion source when changing columns. Various chromatographic performance indicators, such as inertness, and thermal and chemical stability, were confirmed to be unaffected by using this interfa...

متن کاملApplication of Pyrolysis Gas Chromatography/Mass Spectrometry in Lacquer Research: A Review
Examination of thermal degradation of natural and synthetic lacquer films by pyrolysis-gas chromatography with mass spectrometry (Py-GC/MS) is reviewed. Due to the instantaneous heating decomposition, side reactions of internal or intermediate samples hardly occur, and the pyrolysis products can be retrieved without any change. Py-GC/MS has been used to analyze the composition of insoluble poly...
متن کاملInvestigation of Pitch Stabilisation Using Pyrolysis-gas Chromatography-mass Spectrometry
Oxidative stabilisation of mesophase pitch is well known to severely limit the dimensions of artifacts formed from it or, for slightly larger artifacts, to be time-consuming and costly (Gallego, Edie, Nysten, Issi, Treleaven, and Deshpande, 2000). Control and understanding of this step is of very great interest in the production of highly oriented graphitisable material as it could lead to a dr...
متن کاملCatalytic pyrolysis of waste rice husk over mesoporous materials
Catalytic fast pyrolysis of waste rice husk was carried out using pyrolysis-gas chromatography/mass spectrometry [Py-GC/MS]. Meso-MFI zeolite [Meso-MFI] was used as the catalyst. In addition, a 0.5-wt.% platinum [Pt] was ion-exchanged into Meso-MFI to examine the effect of Pt addition. Using a catalytic upgrading method, the activities of the catalysts were evaluated in terms of product composi...
