On a 0.297-mm-diameter column with a 0.874-um-thick stationary phase, an unretained solute passes through the column in 2.87 min, while the analyte requires 7.49 min. Calculate the phase ratio, 6, for this column. B= Number Calculate the partition coefficient, K, for the analyte. K- Number ☐ Determine the retention time, &, of the analyte if a column of the same length with a 0.297-mm diameter and a 0.437-um-thick stationary phase of the same composition and at the same temperature is used for the separation instead.
