SPREADING LAYER AND METHOD FOR PRODUCING AN ANALYSIS ELEMENT SPREADING LAYER

The method involves feeding a porous initial membrane (2) with a bottom side (13), a top side (15), and an initial thickness (D), and cutting the initial membrane at a prescribed distance to the top side. Pores of a spreading layer are fluidically connected to each other such that the pores are perm...

Zusammenfassung:	The method involves feeding a porous initial membrane (2) with a bottom side (13), a top side (15), and an initial thickness (D), and cutting the initial membrane at a prescribed distance to the top side. Pores of a spreading layer are fluidically connected to each other such that the pores are permeable by liquid, and a membrane surface is formed by removing a partial layer of the initial membrane and a fluid outlet side of the spreading layer. Average pore size of the pores at the liquid outlet side of the spreading layer is 1 micro meter. An independent claim is also included for a spreading layer of an optical analysis element for receiving a fluid to be analyzed and for uniformly distributing the liquid to a liquid outlet side.
