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. (10[1])Eddy diffusion (-5[1])and resistance to mass transfer terms calculate the height 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 (10[1])is the retention time, (10[1])which measures how (10[1])fast elution (10[1])occurs. Alumina and silica gel are often used in this technique’s “thin-layer” (10[1])form as a stationary phase. (10[1])For 10 points, name this technique whose “paper” type was originally used to separate pigments. ■END■ (10[1]0[1])
