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 (10[1])with his-tags by applying (10[1])imidazole washes. Eddy diffusion and resistance to mass transfer terms calculate the height of a theoretical plate (10[2])in this technique by the van Deemter (-5[1])equation. The time between injection and the maximum of a peak in this technique is the retention time, which measures how fast elution (10[1])occurs. Alumina and silica gel are often (10[1])used in this technique’s (0[1]-5[1])“thin-layer” (-5[1])form (10[1])as a stationary phase. (10[1])For 10 points, name this technique whose “paper” type was originally used (10[1])to separate pigments. ■END■ (10[2])
