Abstract: A method and a device for supplying a measurement electronics system in a fitting, through which a fluid flows, with electrical energy, which is generated in a turbine by the fluid flowing through the filling, wherein the flow quantities and pressures vary within wide boundaries, typically 1:1000. A pressure control device associated with the turbine controls the pressure of the fluid striking the turbine in such a manner that the electrical energy required for operating the measurement electronics system is generated with a small flow quantity, the pressure loss incurred by the fluid while flowing through the fitting being limited to a maximum value.

Abstract: The present invention concerns a method for the detection of nucleic acids on an analytical element which contains a sample application zone and a detection zone, the analytical element enabling liquid transport from the sample application zone to the detection zone, wherein a sample is applied to the sample application zone of the analytical element and the nucleic acids contained in the sample are denatured and can be detected qualitatively in the detection zone by hybridization with a detection probe and also quantitatively, preferably by means of marker groups. In addition new analytical elements and reagent kits for the detection of nucleic acids are provided.
