Anton Paar has published an application report on the microwave-assisted extraction of additives from polymers.
Polymers are usually stabilised with additives in order to protect them from stress and aging due to environmental impacts.
In terms of production, processing and quality assurance it is important to exactly determine the level of these additives.
Consequently, appropriate sample preparation, i.e. the extraction of the stabilisers from the polymeric matrix, is a crucial step in this analytical process.
Over recent years, old conventional extraction methods like the Soxhlet extraction or simple reflux heating have been replaced by modern, more efficient setups.
One very promising method is the microwave-assisted extraction (MAE), not only because of the tremendous time-saving aspect, but also because of the increased preparative convenience and accurate parameter control.
