This technique is called "high-performance" when it occurs at high pressures.
The UCM hump appears in a form of this procedure which is often followed by mass spectrometry. Acetic acid and water are at the far end of the eluatropic series, which describes this technique. It often involves calculating retention times and the retardation factor. This technique is called "high-performance" when it occurs at high pressures. Silica gel is used in the "thin-layer" form of this technique. It relies on differences in polarity between solute particles, giving the mobile phase differential affinity for the stationary phase. For 10 points, name this technique which can be used to separate pigments on paper.
