Technology cooperation between the University of Luxembourg and metrology specialist Anton Paar: Researchers sell first patent

Anton Paar OptoTec, located close to Hanover, Germany, produces measuring and laboratory instruments for industry and research. The company has acquired the new technology for the optical analysis of materials’ optical and mechanical properties from the University of Luxembourg.

The patented procedure is a result of many years of cooperation, in the course of which the researchers tested the method using prototypes by Anton Paar OptoTec. The method is now to be employed in refractometers. These instruments determine the optical properties of a sample based on light refraction. Refractometers are often used to determine the alcohol or sugar content of aqueous solutions and are applied for maturity checks on wine, for example.

"The new procedure is based on a specific kind of temperature control, which enables a novel determination of a sample’s thermal expansion", explains Prof. Dr. Jan-Kristian Krüger, who invented this new technology together with Dr. Ulrich Müller. "The analysis method we developed – temperature-modulated refractometry – has the additional advantage of considerably convenience. The samples do not have to be changed for the investigation. This saves time and personnel."

Dr. Nils Bertram, General Manager of Anton Paar Optotec GmbH, has agreed to further cooperation with the University of Luxembourg to develop optical measuring procedures. The traditionally close contact with the scientific community forms the basis for the quality of high-precision instruments, says Bertram.
