OMNISEC for Protein characterization

Size Exclusion Chromatography (SEC), is a very popular analytical technique for studying protein molecular weight, oligomeric state, aggregation, and conjugation. Malvern offers a range of multi-detector SEC systems including light scattering for the advanced characterization of proteins. The latest of these is OMNISEC, a complete integrated multi-detector SEC system. OMNISEC offers superior light scattering and refractive index sensitivity for measuring small protein quantities and low molecular weights. It has improved usability with a highly repeatable temperature-controlled (4-60°C) autosampler capable of making injections with zero waste down to just a few microliters. It can be used to measure absolute molecular weight of proteins and peptides as little as less than 1 µg of sample. OMNISEC’s software is intuitive to use and displays multi-detector data in a clear way making it easy to interpret and understand.

What is surface zeta potential and how do I measure it?

Although zeta potential measurements are commonly used to measure colloidal suspensions or molecular solutions, it is also possible to measure the zeta potential of planar surfaces. In this webinar we will introduce the concept of surface zeta potential, show how it can be measured on the Zetasizer Nano using the surface zeta potential cell and discuss some recent applications.

Nebulizers : Achieving bioequivalence using laser diffraction and automated microscopy

This webinar will center on the use of laser diffraction as a technique in characterizing nebulizers, and how it is helpful in understanding the delivery of the drug product. The presentation will also cover the application of automated imaging technology in achieving OINDP bioequivalence and how this technique is complementary to laser diffraction. Finally there will be a case study which highlights the use of these two technologies in characterizing “Pulmicort respules” as a nebulizer formulation.
