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. Eddy diffusion and resistance to mass transfer terms calculate the height of a theoretical plate in this technique (10[1]-5[1])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 measures how fast elution occurs. Alumina and silica gel are often used in this technique’s “thin-layer” (-5[1])form (-5[1])as a stationary phase. For 10 points, name this technique whose “paper” type was originally (10[1])used (10[1])to separate pigments. ■END■ (10[1]0[4])
