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