This application note will describe the analysis of a series of dextran samples ranging in molecular weight from about 1 – 650 kDa. Structural comparisons to other polysaccharides, gum arabic and pectin are presented. Initially discovered by Louis Pasteur in 1861, dextran is a polysaccharide that has found a variety of applications, primarily in the medical field, due to its minimal side-effects and solubility in aqueous media.

Optimizing oxygen delivery improves stem cell treatment of peripheral artery disease.

Just imagine how many analytical problems would be solved if we could increase the resolution of liquid chromatography (LC) from hundreds to thousands or perhaps a hundred thousand compounds?

Two-dimensional photonic crystals combined with spectroscopy shines a light on microbial culprits

The combination of static microscopy and Raman spectroscopy in the Morphologi G3-ID enables automated chemical identification of protein aggregates and other contaminants in a biotherapeutic sample, either in suspension via a thin-path wet cell or on a filter membrane.

The molecular weight, molecular weight distribution and size of three common polymers are measured using OMNISEC. This information can provide insight into the physical properties and behavior of these synthetic polymers.
