A method for programming a flash memory cell comprises providing input data to the flash cell and providing a segmented programming pulse to the flash memory cell. A second section is provided adjacent to the first section that has a header area defining a manifold that supplies fluids to the flow fields of each fuel cell. The device is provided with a mixing chamber that can be closed, wherein a reaction partner, for example a gold conjugate, can be dissolved in the sample for increasing the sensitivity of the test strip.
