Title: METHOD AND APPARATUS FOR THE MEASUREMENT OF THE PROPERTIES OF AN AGGLUTINATION
Abstract:
Method and apparatus for the measurement of the properties of an agglutination, a precipitate (4), or of a corresponding reaction result placed on the bottom (3) of a vessel (1) by means of radiation and of a detector (6)that receives radiation. The beam of measurement (5) coming from the source of radiation passes substantially in the direction of the vertical axis of the vessel, and the intensity of the radiation passing through, or reflected from, the precipitate on the bottom of the vessel is measured. According to the invention, in order to measure the formation, location, and form of the agglutination or precipitate and/or the density or other properties of different points of the agglutination or precipitate, a component field out of the field of the vessel (1) bottom (3) to be measured is measured, the source of radiation is moved in relation to the detector (6) and the vessel (1) so that the component field at each particular time subject to measurement moves along the entire field of vessel (1) to be measured. For the purpose of processing of the information and production of the output, the location of the component field at each particular time under measurement and the intensity of the radiation at the said point are determined at specified intervals by means of a detector (6) that indicates the position at which the beam of measurement arrives on the face of the detector.
