Fields & Applications

The Zetasizer Nano is the world's most widely used light scattering system, for measuring size, zeta potential and molecular weight. Applications range from characterizing high concentration colloids and nanoparticles, through to measurement of proteins and macromolecules in their native state, requiring as little as 12 microlitres of sample. The Zetasizer Nano can be used for the comprehensive characterization of proteins, colloids and nanoparticles, and is simple to use, highly sensitive, versatile and fast! This videos shows how quickly and easily a measurement can be made on the Zetasizer Nano.

Light scattering detectors play an important role in gel permeation chromatography and size exclusion chromatography (GPC/SEC) analysis because of their ability to directly measure molecular weight distribution. Multi angle light scattering (MALS) detectors are often chosen, in some instances because they provide the most accurate data for the measurement of the radius of gyration (Rg), and in others because they have become an accepted industry standard. The launch of Malvern Instruments’ new Viscotek SEC-MALS 20 detector extends commercial choice in this area and draws the technology into the spotlight.

In August, The Analytical Scientist will publish a special issue celebrating the very best images in the field of analytical science. And you have the chance to submit an image that defines your work.

In recent years, the top ten pharmaceuticals sales list has been extensively populated with protein therapeutics, such as monoclonal antibodies and recombinant proteins, that are used to treat various life-threatening diseases, including cancer and autoimmune diseases.

Gun crime is not going away, but current forensic tools are limited at best. We believe that attenuated total reflectance (ATR) imaging could fill a big gap in the crime scene investigator’s armory.

Let’s not boast of “complete proteomes” or “protein coverage” until we correct our ignorance of post-translational modifications. Proteome analysis is more than just identifying and counting proteins.

Removing practical assessments from science education is illogical, say UK chemical engineers

Was an assistant analytical chemistry professor mistaken to instruct graduates not to “thank God”?

Nick Kim gifts us with his very analytical and amusing view of the world around us.

Where does inspiration come from? I mean the insight that leads you to a new invention or that suddenly makes you aware of the solution to a problem?
