A Review of Synthetic Polymer Characterization by Pyrolysis–GC–MS

Characterization of PLA-limonene blends for food packaging applications

“…Although the addition of plasticizer increases the PLA gas permeability, this could be detrimental for food packaging use [3] since polymer barrier properties are of fundamental importance for food packaging applications [20]. López-Rubio & Lagaron, (2009) reported that the addition of the β-carotene to PLA showed a significant plasticization of polymer matrix [21].…”

Pirólisis De Residuos De Bioplásticos: Productos Obtenidos Del Ácido Poliláctico ( Pla)

“…Para identificar los compuestos producidos , la pirólisis es una técnica analítica mucho más sensible que las técnicas tradicionales de análisis térmico como termogravimetría (TGA), o calorimetría diferencial de barrido (DSC) [14,15]. La combinación de la pirólisis acoplada a cromatografía de gases y con detección por espectrometría de masas (Py-GC-MS), resulta una herramienta muy ventajosa para la caracterización de polímeros y sus aditivos [16]. De esta manera, la Py-GC-MS resulta una técnica analítica muy útil para obtener información sobre las reacciones química de degradación de los polímeros inducidas por la temperatura, puede proporcionar información de la cinética de descomposición de los polímeros así como también de la composición de los productos producidos durante la degradación térmica [17].…”

Detection and characterization of pyromarkers of smoked drugs of abuse

“…It has long been recognized that small samples, typically less than 1 mg, good heat transfer and rapid heating of the pyrolysis element are essential in achieving reproducibility. 77,78,83,89 With same instrumental conditions and the same amount of sample, the reproducibility can be good with replicate analysis with relative standard deviations less than 1% frequently reported. 78,83 Calibration is typically necessary by using internal standards, external standards, or a standard addition procedure.…”

“…Quantitative analysis is applied more frequently in polymer analysis, for example, in the determination of the amount of a specific polymer in a given complex matrix, such as a composite material, inorganic matrix, etc. 78,89,90 Quantitative measurement of a pyrolysis product can be used successfully even for the analysis of other organic molecules. 78,89 In order to have a reliable quantitative result by Py-GC/MS, an important requirement is the repeatability of the analysis.…”
