  • Microfluidic element with multi-functional measuring chamber for the analysis of a fluid sample
    Patent number: 8759081
    Abstract: A test element, analytical system and method for optical analysis of fluid samples is provided. The test element has a substrate and a microfluidic channel structure, which is enclosed by the substrate and a cover layer. The channel structure has a measuring chamber with an inlet opening. The test element has a first level, which faces the cover layer, and a second level, which interconnects with the first level such that the first level is positioned between the cover layer and the second level. A part of the measuring chamber extending through the first level forms a measuring zone connecting with a part of the measuring chamber that extends partially into the second level, forming a mixing zone. Optical analysis of fluid samples is carried out by light guided through the first level parallel to the cover layer, such that the light traverses the measuring zone along an optical axis.
