ABSTRACT:
The present invention provides a process for carrying out an analytical determination by mixing and incubating a sample solution with at least one reagent and measuring a parameter in the reaction mixture, the sample solution being transported from an application point to a measurement point, wherein a sample solution is first transported to a soluble dry reagent, with at least partial dissolving of the latter, and then further transported to a measurement point, the transport taking place by two different forces, whereby, at least on a part of the transport path, it is brought about by a surface force acting on the solution as a first force, which, for the regulation of the transport velocity or transport direction, is superimposed by a centrifugal force and/or pressure force as a second force which, depending upon which transport state of the fluid is to be adjusted, is made greater or smaller than the first force.
