The addition of the NanoSight range of nanoparticle characterization instruments adds another orthogonal technique to the suite of tools available to the particle scientist. Nanoparticle Tracking Analysis (NTA) is a unique and patented technology that enables rapid and simultaneous multi-parameter analysis and characterization of many different types of nanoscale particles. With the ability to visualize individual particles in solution, then analyze for size and count/concentration, both under scatter and fluorescence mode, NanoSight systems are closely aligned with Malvern’s market-leading Zetasizer range, extending Malvern’s solutions for those working at the nanoscale. This webinar will serve as an introduction to the technique for Malvern’s Zetasizer users. The basics of the science will be covered, with numerous examples and comparison to existing Zetasizer capabilities and results. NanoSight’s unique technology has become accepted in laboratories around the world and is widely cited in research publications. With rapid advances in nanomaterials and the life sciences, in biopharmaceuticals especially, the demand for new technologies to answer continually evolving analytical challenges has never been greater. This is a very exciting time and by bringing together complementary, leading edge technologies, Malvern continues to focus on delivering the analytical tools which laboratories so urgently need.
