Polymers and polysaccharides are classes of huge use, from ingredients in controlled release formulations, to their use in construction industry, as well as in packaging materials for food products – just to mention some examples. For many of the applications, the size and molar mass of the polymer or polysaccharide impact their performance. Therefore, the knowledge and control of these parameters are important to have control of the function of the product.
At SOLVE we often work with everything from commonly used compounds to challenging polymers that are difficult to characterize. A few examples of the type of information that be obtain are given below:
1) Size separation of a high molar mass dextran sample by AF4-MALS-RI.
2) Separation of a technical grade carboxy methyl cellulose (CMC) (polyelectrolyte) sample by AF4-MALS-RI.
3) Conformation plot from the analysis of the CMC sample.
