Question

What variables are likely to affect the selectivity factor$\alpha$ for a pair of analytes?

Short answer

Set temperature, stationary phase in the column, uses of different chemical reagents like surfactant, complexing agents, and ion-pairing reagents are likely to affect the selectivity factor $\alpha$for a pair of analytes.
