Institute for Macromolecular Chemistry

Welcome!

Welcome to team Makro! We are polymer scientists – from polymer synthesis to polymer physical chemistry to polymer engineering and applications. Our fundamental research focuses on novel synthetic methods and advanced applications of complex, controlled, bioinspired, biobased and bioactive macromolecules.

Plastics based on renewable raw materials, energy-efficient lightweight materials, sustainable materials for flexible electronics, interactive materials for biomedical applications and the development of complex, quasi-living material systems are just some of our research topics. If you are interested to learn more, check out the research groups headed by Laura Hartmann, Stefan Naumann, Stephan Schmidt and Prasad Shastri.

If you want to learn more why Freiburg and our institute are where polymer research started, check out the history of the institute here.

Dive into the fascinating world of macromolecular chemistry, where science meets innovation and application! This field explores the synthesis, structure, and properties of large molecules – or what we call polymers, and materials made from polymers such as plastics. We live in a world where polymers and plastics are an essential part of our everyday live, our health and well-being. However, we also know that synthetic polymers possess many challenges for our environment. By understanding how polymers are made, why they have unique properties and how we apply them, we can support and work on the development of new and better and more sustainable polymers and materials.

Embark on a journey of discovery and creativity, and be part of shaping the future of materials science!

Lectures

The “Molecular Analytics of Polymers” Shared Facility consolidates the service units at the Institute of Macromolecular Chemistry—which have been active for more than 20 years—in the fields of gel permeation chromatography and mass spectrometry.

Gel permeation chromatography (GPC) determines parameters such molecular weight distributions for synthetic or bio-derived polymers. MALDI-ToF mass spectrometry (MS) provides detailed information regarding their chemical structure and composition.

The Molecular Analytics of Polymers (MAP) Facility makes these high-performance methods available to the Faculty of Chemistry and Pharmacy, and—as a service—to the entire university as well as external partners.

Registration for MAP Users

Please note that registration is required before submitting a sample or measurement for the first time.

To begin the registration process, please send the registration form in form a brief email to gpc-service@makro.uni-freiburg.de.

After successful registration, you will receive the following training sessions (applies to both service and user operation) from the service manager:

Training in sample preparation (good practice)
Training in sample evaluation (good practice)

If you register for user operation, you will additionally receive instrument training from the operators as a prerequisite for user operation. This instrument training must be repeated annually.

Available Methods

Sample Preperation

Samples are accepted exclusively in screw-top glass vials with metal caps (exact sample model information is provided by the service-manager)

The sample concentration is determined and communicated by the GPC Service at the start of the project.

You must dissolve all samples in the mobile phase at a suitable concentration.

N,N-dimethylformamide + LiBr and aqueous buffers for sample preparation are provided by the GPC laboratory. Please bring a suitable, clean, and labeled container; a maximum of 100 ml will be dispensed.

Ensure that your sample is completely dissolved; suspensions will not be measured.

Sample Submission Process

Please check when the method you need will be performed.

The schedule is posted above the sample table and can be viewed HERE. Please note the submission deadlines.

For the first sample submission, please read the following document.

Sample drop-off location: Institute of Macromolecular Chemistry, Stefan-Meier-Str. 31, basement; The sample table is located next to the fire extinguishers.

The samples are entered in sequential order on the sample sheet provided and placed in the same order in the sample rack of the respective GPC system.

The following information must be provided:

First and last name (If you are submitting on behalf of another person, their name must be entered)

Research group

Sample designation (Short, clear designations, in sequential order)

Concentration in mg/ml

Solvent – enter either the aqueous buffer or the organic solvent to be used.

Required Calibration – Specify here which calibration is to be used (e.g., PMMA). If no specification is provided, the standard calibration for the respective method will be used.

Remarks – here, always specify the type of polymer (e.g., PEG, PLA, PMMA-PS, etc.) and, if possible, a rough estimate of the expected molecular weight (e.g., < 5,000 Da, ~ 100,000 Da, > 1,000,000). For measurements with Malls detection, enter the dn/dc of your sample here! Special requests, such as a suitable wavelength, should also be entered here.
