Polymers are sensitive molecules. Depending on the polymer architecture or copolymer composition, it is possible to have bonds present along the polymer chain that can easily be broken.

In polystyrene solutions, breaking the polymer chains can happen, just by stirring a high molecular weight viscous solution.
Dispersive Liquid-Liquid Microextraction: A Review and Roundup of Green Sample Prep Advancements
May 15th 2024The still relatively new technique has distinct advantages, but a few of those benefits make it incompatible with some of the currently accepted principles of green sample preparation.
Reflecting on the Influence of the Current State of Sample Preparation on GC, Part 2: Techniques
May 9th 2024In this installment, we examine trends in the use of sample preparation techniques through the lens of instrumental analysis by gas chromatography (GC) and GC–mass spectrometry (GC–MS).
