The 'Discussion group Separation methods for Polymers' (DSP) is an active subdivision of the Section Analytical Chemistry (SAC) that focuses on the separation and characterization of synthetic polymers and biopolymers.
DSP aims at providing a platform for scientists from both industry and academia to interact, share experiences and to discuss new developments.

All chromatographic separation methods for polymers are in scope of the DSP meetings, ranging from size-exclusion chromatography (SEC/GPC) to end-group analysis by liquid chromatography at critical conditions (LCCC).

Also particle size analysis techniques, such as hydrodynamic chromatography (HDC) and field-flow fractionation (FFF), are often discussed, as well as coupling of separation methods to high-end techniques, such as mass spectrometry (MS), infrared (IR) and nuclear magnetic resonance (NMR) spectroscopy.

Twice a year a meeting/symposium is organized, where members present their research and share the difficulties in polymer separation.

If you are interested in becoming a member of the DSP and attending one of the meetings, register using the following form: DSP Registration Fall meeting 2025 

Membership of the DSP, as well as attendance of most meetings is free of charge.

The next meeting of the Discussion group on the Separation of Polymers will be held in Fall of 2026 .
