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 and resistance to mass transfer terms calculate the height of a theoretical (10[1])plate in this technique by the van (10[1])Deemter equation. (-5[1])The time between injection and the maximum (10[1])of a peak in this technique is the retention time, which measures how fast elution occurs. (-5[1])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])
