Malvern & Postnova to Deliver Solution for Characterizing Challenging Particulate Systems

Malvern Instruments and Postnova Analytics recently announced they are co-operating 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.

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 gel permeation chromatography/size exclusion chromatography (GPC/SEC) range.

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.

“I am very pleased this exclusive co-operation with Postnova means that customers of both our companies will be able to access these powerful analytical techniques, secure in the knowledge that they are backed by the excellent technical and applications support provided by both Postnova and Malvern,” said Paul Clarke, Product Group Manager at Malvern Instruments.

Postnova Analytics is the global market leader and inventor of FFF developing instruments since the 1980s. Its solutions are setting the standards in the environmental, nanotech, polymer, and biotech markets and are ideally suited for high resolution separation, fractionation, and characterization of proteins, biopolymers and nanoparticles. Postnova is the sole supplier of completely integrated FFF Light-Scattering solutions, including award winning Instruments, such as Thermal FFF, Centrifugal FFF, and Flow FFF coupled with Dynamic Light Scattering (DLS).

Malvern Instruments is a market leader in measuring performance-controlling material properties. These include particle size, particle shape, zeta potential, molecular weight, size and conformation, rheological properties, and chemical identification. Malvern delivers the systems, support, and expertise that ensure the analytical integrity and productivity needed to drive research, development, and manufacturing.
