Contact Angle Measurements in Deepenings
Contact angle measurements in holes, bowls and wells were up to now not possible due to their specific geometry. With the new TDA10A, now the wetting properties of these samples can be characterised precisely. By using a new arrangement of the measurement system and the piezo dosing system these new applications were made possible.

Contact angle measurements in the wells of micro-titer plates can be performed as well as measurements on the concave side of contact lenses or on small areas of micro-mechanical devices.

Assessing the cleaning ability of aqueous surfactant solutions on soiled hydrophobic textile fabrics by using contact angle and surface tension measurements
This article presents a practical way of making an estimation based on surface tension measurements between dirt components and the cleaning solution as well as on contact angle measurements made on hydrophobic textiles; this makes it possible to predict the cleaning effect.

Adhesion Energy and Interfacial Tension – Two Related Coating/Substrate Interfacial Properties. Which is More Important for Your Application, and Why ?
The major reason for determining surface energies and surface polarities for coatings (including adhesives and inks) and substrates is as a basis for modification of either one or the other (or possibly both) to improve either wetting, spreading, or adhesion. Two important interfacial parameters are typically gained from such work: the physiochemical adhesion energy between the coating and the substrate, and the interfacial tension that remains, once the substrate/coating interface is formed. The former property (adhesion energy) has much to do with how favorable the formation of such a substrate/coating "bond" is. The later property (interfacial tension) has to do with how difficult such a bond will be to break, once it is formed.

Increased activities in application support

- Surface Science Contract Lab in U.S. to Better Serve the Needs of Growing Customer Base

- Surface science specialist adds to the strength of our rapidly expanding application laboratory in Hamburg, Germany

In order to better serve KRUSS customers' contract laboratory needs, KRUSS has a strategic alliance with company Augustine Scientific, Ohio, Dr. Christopher Rulison. Augustine Scientific exclusively uses KRUSS instrumentation for all surface tension and contact angle measurements. Dr. Rulison will operate in close partnership with KRUSS’ International facilities to provide the best data analysis for our customers as a precursor to, or in lieu of, instrumentation purchases.

To support the advancement of the field of surface science, Christine Bilke-Krause joined KRUSS in June 2002 as the head of our Hamburg, Germany application development laboratory. Mrs. Bilke-Krause brought to KRUSS more than a decade of surface science expertise gained while studying at Humboldt University of Berlin and the University of Leipzig as well as several years of corporate surface science experience.

In addition KRUSS continues to operate sales demonstration and application development laboratories in Charlotte, NC, and Palaiseau, France.

No nitrogen cooling required / Convenient operation: only one calibration for the measurement range from "sulfur-free" to 500 mg/kg
February 2003 With the energy-dispersive XRF system SPECTRO XEPOS for the analysis of sulfur in fuels, SPECTRO advances into measurement ranges that were previously restricted to the significantly more expensive wavelength-dispersive XRF instruments. The bench top XEPOS achieves a detection limit of less than 1 mg/kg for sulfur in fuels.
Recently there has been an international push to reduce the limits of sulfur in fuels. By 2010, the maximum allowed content of sulfur will decrease to 10 mg/kg in gasoline and 50 mg/kg in diesel fuel. For analyses methods used in the petrochemical industry this means, in turn, that the detection limit should be a factor of 10 less than the required limits. Thus, conventional energy-dispersive X-ray fluorescence analysis, the cost-effective and user-friendly standard method for oil laboratories, will become obsolete.
The technologically advanced ED-XRF SPECTRO XEPOS, however, achieves the required sulfur detection limit of less than 1 mg/kg. The primary reason for this can be found in the proprietary polarized excitation radiation, which enables an almost complete suppression of the spectral background, increasing sensitivity by a factor of four versus conventional energy-dispersive X-ray fluorescence spectrometers. A high-resolution, peltier cooled, Si drift chamber is used as a detection system, eliminating the need for liquid nitrogen cooling.
