Products displayed will include the recently launched Mastersizer 3000, Morphologi G3 and Zetasizer Nano particle characterization systems; the Kinexus rheometer; Insitec online analyzers; Viscotek GPC/SEC systems; and Postnova’s FFF (Field Flow Fractionation) solutions. Used together, Malvern’s Zetasizer Nano and Postnova’s FFF systems provide information not accessible by other means, and are highly complementary to Malvern’s Viscotek GPC/SEC range.
A key area of Malvern expertise is in dispersion stability and Malvern is the only company whose analytical instruments cover the full array of measurements necessary for its comprehensive determination – this includes particle size and shape measurement, zeta potential and rheological parameters. As well as having the opportunity to discuss dispersion stability issues with Malvern’s expert teams at ACHEMA, visitors to the Malvern stand can find out more about the application of particle and molecular characterization using dynamic light scattering with the Zetasizer series and Viscotek GPC/SEC systems, dynamic imaging with the Sysmex FPIA-3000, and Kinexus rheometers for the measurement of a wide variety of rheological parameters.
In support of this, Malvern recently announced a co-operation with Postnova Analytics (Landsberg/Lech, Germany) to deliver the combined FFF (Field-Flow Fractionation) and DLS (Dynamic Light Scattering) solutions that today provide critical insight when characterizing a number of challenging particulate systems. Such systems include complex, aggregated, surface-coated and heterogeneous particles, as well as larger polymers, and aggregated, cross-linked, nano-particles and fibrillated proteins.
FFF enables the separation of particles that are too large for analysis by GPC/SEC, and the addition of the Zetasizer Nano as a DLS detector allows the subsequent measurement of absolute particle size. In comparison with batch measurements of DLS using the Zetasizer Nano alone, the addition of FFF considerably increases the resolving power of DLS, extending the range of applications for which it can provide highly detailed information.
