• 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 Silicone Technologies for Skin Care
  

  In today's competitive skin care market, consumers look for a range of benefits, superior aesthetics and cost effectiveness. In response, formulators strive to create products that are multifunctional, easy to use and effective in small quantities. At the same time, the most successful products deliver benefits that stand out from those of the competition. Creams, lotions and color cosmetics must be easy to spread and comfortable to wear, without feeling tacky or greasy. Silicones have been popular ingredients in skin care products for more than fifty years. These versatile materials are known for their emolliency, wetting and spreading characteristics and ability to provide unique aesthetics. As technology continues to evolve, silicones increasingly offer multifunctional, high performance properties. This article reviews some of the newest silicone technologies available for the formulation of innovative skin care products more

• Automated Dynamic Light Scattering
  

  DLS analysis is a widely applied, non-invasive method for measuring the effective size of molecules in solution. This technique yields valuable information for the characterization of molecules and particles. It facilitates formerly laborious and time consuming measurements, e.g. screening for aggregates or determining optimal crystallization conditions for proteins. The Wyatt Plate Reader is the instrument of choice for any application where molecular size, stability and aggregation are of interest. It reads industry standard microplates with up to 1536 samples automatically and temperature-controlled, if desired. The applications of the technique are wide ranging and include many of the fastest growing areas of research - proteins, biomaterials, liposomes and micelles as well as the established uses for particle sizing and aggregation detection. Conscious of the numerous characterization challenges in the area of drug delivery systems and therapeutic antibodies more
