Formula and explanation
Formula: t R = t M (1 + k'), where t R is the retention time, t M is the dead time (time for an unretained component to pass through the column), and k' is the partition ratio (capacity factor). Applicable conditions: Chromatographic separation process. Description: Describes the relationship between a component's retention time in a chromatographic column and its partition ratio, forming the basis for chromatographic qualitative analysis. The partition ratio k' = K · (V s)/(V m), where K is the distribution coefficient, V s is the stationary phase volume, and V m is the mobile phase volume.
