The invention relates to a fluid analysis module that comprises for blood analysis: a module housing with a fluid inlet port; at least one fluid sensor that is integrated within the module housing and comprises a sensor surface that is able to make a fluidic connection with the fluid inlet port; a chamber integrated within the module housing. The chamber can be brought into a fluidic connection with the sensor surface of the at least one fluid sensor. At least one first liquid reservoir attached within the chamber which is able to be brought into a fluidic connection with the sensor surface of the at least one fluid sensor; and at least one module housing surface, on which an elastic, fluid-tight separating wall that is embodied in membrane-like fashion is attached At least in portions, under a separating wall at least one fluidic functional configured as a flow valve and at least one fluidic functional element configured as a delivery pump is attached so that the fluidic functional elements are operable by local mechanical deformation of the separating wall: a) only deliver fluid from the fluid inlet port into the chamber via the sensor surface and b) only deliver a liquid housed in the liquid reservoir from the liquid reservoir into the chamber via the sensor surface.

Fluid analysis module and fluid analyzer

Disclosed is a method for quality control of a material layer, which involves providing the material of the layer with an agent for absorbing an electromagnetic radiation, irradiating the surface of the layer with an electromagnetic radiation, and measuring the amount of light emitted by the material layer, for example, reflected radiation or fluorescence radiation.

Method for the quality control of material layers

The invention relates to a sensor for detecting substance concentration or activity or for determining the presence of substances based on electrochemical reactions. The electrochemical sensor comprises an electrode with surfaces inside the electrode, wherein electrochemical detection reactions occur. Said sensor guarantees high flow densities and is suitable for miniaturization. A substance-recognizing agent is advantageously placed in the electrode in contact with the inner surfaces. This enables not only short response times and long service life but also measurements with excellent linearity.
