SPREADING LAYER AND METHOD FOR PRODUCING AN ANALYSIS ELEMENT SPREADING LAYER |
摘要 |
Methods of producing an analysis spreading layer for absorbing a liquid to be analyzed, by: supplying a porous membrane having a bottom, a top and a thickness D, the size of the pores of the membrane increasing over its thickness D; cutting the membrane at a predefined distance, the spreading layer being a sublayer with a thickness d less than the starting thickness D, the pores of the spreading layer having a fluid connection to one another in such a manner that it is permeable to a liquid. The membrane surface is formed by removing a sublayer of the membrane being the liquid outlet side of the spreading layer. The mean size of the pores on the liquid outlet side is at least 1 μm. |
