This process can be characterized for organic compounds by the Kovats index, which uses the peaks of two known alkanes to determine the retention index of a sample. One type of this technique exploits capillary action on an activated glass plate, while in another type of this process, pressurized gas forces the elutant through small grains of silica to increase the flow rate. That "flash" type of this method is an example of the "column" type, which uses a solid stationary phase and a solvent as the mobile phase. For 10 points, name this analytical technique used to separate mixtures, often in
