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.

New developments are mobilizing Raman, mid-infrared and near-infrared spectroscopy for a whole host of innovative handheld applications.

Manufacturing is getting smarter; only a cross-discipline approach will ensure the success of tomorrow’s processes.
