Chapter 26, Problem 26.15QAP

Interpretation Introduction

(a)

Interpretation:

Retention factor of each case should be calculated.

Concept introduction:

$\text{K = }\frac{{\text{t}}_{\text{R}}{\text{-t}}_{\text{0}}}{{\text{t}}_{\text{R}}}$

K = retention factor

T_R = retention time

T₀ = nonretained time

Interpretation Introduction

(b)

Interpretation:

Distribution constant for each case should be calculated.

Concept introduction:

$K_A=\frac{k_A{V}_M}{V_S}$

K_A = distribution constant

k_A = retention factor

V_M = Volume in mobile phase

V_s = volume in stationary phase
