Break-through in High Temperature Polymer Separation Technology

The AF2000 HT Series is the world's first commercial HTFFF instrument available and was invented and patented by Postnova Analytics. High Temperature Field-Flow Fractionation is a brand new technology ideally suited for the advanced separation of high molar mass polymers, such as polyethylene and polypropylene. more

  • New technique to sharpen microscope images

    The complexity of biology can befuddle even the most sophisticated light microscopes. Biological samples bend light in unpredictable ways, returning difficult-to-interpret information to the microscope and distorting the resulting image. New imaging technology developed at the Howard Hughes Medical more

  • Vibrational molecular pathology

    IR and Raman spectral imaging can distinguish between tissue types, disease types and stages, and even identify the primary tumors from spectral patterns observed in metastatic cells. Furthermore, these techniques can be used in the detection of circulating tumor cells. Spectral histopathology proce more

  • A new Concept in Microscopy: Self-reconstructing Laser Beams

    It’s a familiar situation for all car drivers. In the autumn, when the roads are foggy, visibility drops below 50 metres. The light of the car’s headlights are scattered by the drops of fog, meaning we can’t see objects further away because the light can’t reach them. This everyday example illustrat more

  • Field-Flow Fractionation - The Universal Separation Principle for Particle and Macromolecule Characterization

    High molecular weight polymers, bio molecules or particles in a range of a few nanometers up to several microns are more and more important in science and technology. Many applications are based on the specific properties of these materials. For this reason, an exact knowledge of the molar mass or particle sizes distribution is essential for later application as well as for optimization of the production processes or quality control. In addition the knowledge about the chain structure of macromolecules or biopolymers as well as about the shape of particles is often necessary. For this reason those samples, which often can be very complex systems, have to be separated according to parameters such as e.g. hydrodynamic volume or molecular weight. After the separation process the resulting narrow dispersed fractions are detected with different techniques. more

  • Measurement of Nano particles and Proteins

    Colloid emulsions in their native environment require particle size determination in high concentration since there are concerns about changes in sample morphology upon dilution eg break up of aggregates. For proteins and other samples with very low concentration and for weakly scattering samples high sensitivity is required. New technologies offer both. more

  • Dynamic Light Scattering - an Important Tool for Protein Crystallography and Nanotechnology

    Dynamic Light Scattering (DLS) is an established technique in the field of protein crystallography. DLS is used to measure hydrodynamic sizes, polydispersities and aggregation effects of protein samples. These are important parameters for the crystallisation of proteins. DLS is also used in the nanotechnology research for the accurate and fast size measurement of nanoparticles made of different materials. more
