One index used in this technique, which normalizes n-alkanes to multiples of 100, is named for Ervin Kováts. One form of this technique isolates proteins with his-tags by applying imidazole washes. Eddy diffusion and resistance to mass transfer (-5[1])terms calculate the height (10[1])of a theoretical plate in this technique by the van Deemter equation. The time between injection and the maximum of a peak in this technique is the retention (10[1])time, which measures how fast elution occurs. Alumina and silica gel are often used (10[1])in this (10[1])technique’s “thin-layer” form (10[3])as a stationary phase. For 10 points, name this technique whose “paper” type was originally used (10[1])to separate pigments. ■END■ (10[1])
