Patent number: 8624599Abstract: An analysis system (1) for the analysis of a sample, comprises a gel permeation chromatograph (14) that is coupled with a nuclear magnetic resonance (=NMR) spectrometer. The chromatograph (14) has a gel permeation chromatography (=GPC) separating column system (6a) that is filled with porous particles (21). The NMR spectrometer is configured as a low-field NMR spectrometer (8) with a permanent magnet system (9) for generating a B0 field of the NMR spectrometer. The low-field NMR spectrometer (8) comprises a shim system (10) with which homogeneity of the B0 field of at least 0.5 ppm can be achieved in a right circular cylindrical sample volume (27) having a diameter of at least 5 mm and a length of at least 15 mm. The system permits the quantitative and qualitative chemical analysis of samples containing substances of different molecular size using a less expensive apparatus.Type: GrantFiled: February 14, 2011Date of Patent: January 7, 2014Assignees: Bruker BioSpin GmbH, PSS Polymer Standards Service GmbH, Karlsruher Institut fuer TechnologieInventors: Andreas Kamlowski, Thorsten Hofe, Markus Cudaj, Manfred Wilhelm, Gisela Guthausen

Patent number: 8339260Abstract: A hazardous area in the region surrounding a reel transport of a reel changer is secured. A contactless protective device is located at the access boundaries of the region. This protective device can be deactivated for feeding and/or removing a known object and comprises an evaluation unit. The protective device is configured as a light curtain that is comprised of a plurality of light beams that run in parallel to each other. The evaluation unit includes an assembly for detecting the sequence of the interruption of the light beams during the feeding and/or the removal of an object. Based on the detected sequence of interruption of the light beams, a known object, that is permitted to access the hazardous area, is detected. The protective device is deactivated in this situation. Securing the hazardous area further includes the provision of a second contactless protective device that is permanently active.Type: GrantFiled: July 28, 2009Date of Patent: December 25, 2012Assignee: Koenig & Bauer AktiengesellschaftInventors: Katja Paula Krieger, Manfred Wilhelm Maierhöfer, Klaus Karl Müller, Josef Herbert Olbort, Karlheinz Rahner, Senad Ugljesa
