Patent number: 8432550Abstract: A method for the assessment of quantity and quality parameters of biological particles in a liquid analyte material. The method comprises applying a volume of a liquid sample to an exposing domain from which exposing domain electromagnetic signals from the sample in the domain can pass to the exterior, and exposing, onto an array of active detection elements such as CCD-elements, a spatial representation of electromagnetic signals having passed from the domain, the representation being detectable as an intensity by individual active detection elements, under conditions permitting processing of the intensities detected by the array of detection elements during the exposure in such a manner that representations of electromagnetic signals from the biological particles are identified as distinct from representations of electromagnetic signals from background signals.Type: GrantFiled: March 28, 2012Date of Patent: April 30, 2013Assignee: ChemoMetec A/SInventors: Frans Ejner Ravn Hansen, Martin Glensbjerg, Börkur Arnvidarson, Jesper Myron Jeppesen

Patent number: 6970246Abstract: The present invention relates to an apparatus and a method for detecting the fluorescence of a sample, wherein the apparatus comprises excitation light source located on the same side of the sample as the detecting means. The apparatus may be constructed as a single-sided as well as a double-sided system, wherein the double-sided system comprises double-sided excitation system and/or double-sided detecting system. The double-sided system may also be a combination of fluorescence system and conventional microscopy. The apparatus may be used for analysis of various types of biological material, liquid as well as solid material, and various other types of material suitable being analysed through fluorescence studies.Type: GrantFiled: April 11, 2001Date of Patent: November 29, 2005Assignee: ChemoMetec A/SInventor: Frans Ejner Ravn Hansen
