Vorrichtung und Verfahren zur Durchfuehrung statischer und dynamischer Streulichtmessungen in kleinen Volumina

DE 102007031244 B3 UPAB: 20090120 NOVELTY - The device has a focusing element (4) e.g. parabolic reflector, to focus an electromagnetic ring radiation (3) on a specimen (11), where a scattered electromagnetic radiation (15) from the specimen is guided to a detector (9) e.g. spectrometer, by a microscope lens (5), a focusing lens (7) and a fiber optical waveguide (8). The element focuses the ring radiation on a focus point (12) within the specimen through a radiation forming device (2). The scattered radiation is detected by the lenses and the waveguide, where the scattered radiation spreads within an area of the ring radiation. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for executing scattered light measurements. USE - Device for executing scattered light measurements, in a measuring system (claimed), for characterization of colloidal particles for a cosmetic product, polymers or adhesives and in a food industry, and for clearing structures of complex proteins and bio-molecules. ADVANTAGE - The focusing element focuses the electromagnetic ring radiation on the focus point within the specimen through the radiation forming device, where the scattered radiation is detected by the lenses and the waveguide, and the scattered radiation spreads within the area of the ring radiation, thus effectively suppressing unwanted portions of the radiation, and examining a number of specimen with a very small volume in a systematic, automatic, and rapid manner
