One problem associated with this technique is known as tailing, but can be avoided by increasing the polarity of the solvent. The flash type of this technique uses air pressure, and the most common variety usually begins with spotting and is used to calculate the retardation factor, or the R-sub-f value. In general, this technique uses two phases, one of which is stationary and the other moving, in order to separate components of a mixture. For 10 points, name this laboratory technique, types of which include column and
