The relative retention, $\alpha$, is defined as the ratio of the adjusted retention times of two solutes, thus $\alpha = \frac{t'_2}{t'_1}$. Given $\alpha = 1.35$ and $t'_2 = 293$ s, we can solve for $t'_1$ as follows: $t'_1 = \frac{t'_2}{\alpha} = \frac{293}{1.35} \approx 217$ s.

The Relative Retention Between Two Solutes,1 and 2,is α\alphaα = 135If the Adjusted Retention Time for Solute 2 Is 293

The Relative Retention Between Two Solutes,1 and 2,is $\alpha$ = 135If the Adjusted Retention Time for Solute 2 Is 293
