• 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

• New since 5000 years
  

  Although the ancient Egyptians already used inks 5000 years ago, inks and their properties have been continuously improved and refined over thousands of years. Nevertheless, the basic principle of tinta acqua (colored water) remains the same. Today, in addition to inks based on dissolved dyes, there are many which contain pigments in solid form. Unlike dyes, pigments do not dissolve in the medium but are present in dispersed form, e.g. as suspensions. Pigment-based inks have an advantage over those containing dissolved dyes: after drying, they are light-stable and less sensitive towards water or other solvents. They also have higher color intensity. This is an important criterion for the 'permanent document' quality rating more
