Investigation of Biodegradable Plastics using EGA and Pyrolysis-GC/MS

This application note follows the pyrolysis application decision making tree with EGA and pyrolysis to study biodegradable plastics.

With the rapidly increasing production of disposable plastic products, plastic pollution has become a pressing environmental issue. Biodegradable plastics, which can be decomposed by the action of living organisms, are part of the solution to this problem¹. In this application note, EGA plus analytical pyrolysis was used investigate biodegradable polymers.

For analysis, 100μg of polylactide standard was first added into a DISC (Drop-In-Sample Chamber) tube and then analyzed using Evolved Gas Analysis (EGA) on a Pyroprobe 6150 and a vent free adapter as an initial screening step. Using the information from this step, single step pyrolysis GC-MS was performed on different types of biodegradable consumer products.
