Abstract
A sample application zone and detection zone are arranged on a pile-like complex made of a fleece and a porous membrane which are in a direct or indirect contact that enables passage of liquid through the contact area and the membrane is a polyamide, polyvinylidene difluoride, polyether sulfone or polysulfone membrane which transports liquid significantly slower over the area than the fleece.
