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