  • Accurate Mass and TIPTM: Two Dimensions for Elemental Composition Determination: microTOFTM Featuring Unique TIPTM

    The ESI-TOF mass spectrometers micrOTOF and micrOTOF focus do not only provide accurate mass measurements but additionally describe the True Isotopic Pattern TIPTM. For molecular formula generation this unique combination significantly reduces the number of possible formula candidates and the elemental composition of compounds with molecular weights far higher than 500 Da can unequivocally be determined 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

  • Improvement of power generation efficiency of solar cells and evaluation by fluorescence spectroscopy

    The light in the high-radiance wavelength region of the solar spectrum is not utilized effectively by silicon crystal-based solar cell modules. "Fluorescent materials" convert the ultraviolet component in the sunlight into light in the longer wavelength region where this solar cell modules can generate power. This article describes an example, how the efficiency of a fluorescent material can be evaluated, using a fluorescence spectrophotometer equipped with an integrating sphere, and a special program, which allows the determination of quantum yields of powders in a very comfortable way. more

  • Determination of the Glass Transition

    Glass transitions occur in all non-crystalline or semicrystalline materials and lead to significant changes in material properties such as thermal expansion, the specific heat capacity or modulus. Because the glass transition is very sensitive to chemical and physical structure, it can be used to ch more
