Continuous monitoring of chemical products with an innovative matchbox-sized laser

Professionals in the fields of science, technology, engineering, and mathematics – STEM – have great potential to boost scientific literacy in schools. Can you make time to pass on years of experience and educate the next generation?

The techniques of laser diffraction and automated particle imaging support the fast, cost-effective development of nasal spray products, simultaneously providing the data required for regulatory compliance. This paper examines their application.

GPC/SEC is mainly used for the characterization of macromolecules including synthetic and natural polymers (including polysaccharides) as well as proteins or RNA/DNA. This white paper provides an introduction to the technique in 30 minutes.

In this application note, we show that Malvern’s OmniSEC software can now communicate with Waters Empower® for the seamless exchange of sample sequences. This allows OmniSEC to follow the injections performed by a Waters SEC system and to synchronize data collection. A selection of proteins was used to demonstrate the measurement of protein molecular weight, oligomeric and aggregation state.

Four different polymers are analyzed by GPC/SEC to investigate the effect of molecular weight, dispersity and molecular structure on the final properties of the polymer.
