In paper and thin-layer chromatography, the sample is often applied many times to the same spot, and the solvent is allowed to evaporate between applications. The gases are passed through a long, narrow (and most often, coiled) tube either packed with a porous stationary phase or whose inner walls are coated with a stationary phase, and the analyte components are detected as they emerge from the far end of the tube. As a result, cork oak forests become susceptible to pest attack, which accelerates the onset of decline.
