ABSTRACT The present invention provides a process for carrying out analytical determinations by mixing and incubating a sample solution with at least one reagent solution and optical measurement of one parameter in the incubated reaction solution mixture, mixing, incubating and measuring being carried out during the action of a centrifugal force, wherein, under the influence of the centrifugal force, the sample solution is brought together with a soluble dry reagent, with at least partial dissolving thereof, and the mixture or the solution is forced centrifugally through a plurality of small hollow spaces, the centrifugal force and the flow resistance of the small hollow spaces being so adapted with regard to one another that a complete dissolving and mixing of the reaction components and possibly incubation takes place before the reaction solution passes from the small hollow spaces into a measuring chamber in which the measure-ment is carried out. The present invention also provides an insert element for a centrifugal analysis rotor, wherein it comprises at least one analysis reagent in dry form and has a plurality of very small interconnecting hollow spaces which connect a sample providing chamber with a measuring chamber. |
