Which is NOT true for solute retention? A)Retention time,t_r,is the elapsed time between injecting the sample to the arrival of a sample component at the detector minus the dwell time between the end of the column and the detector. B)Adjusted retention time is t_r^' = t_r - t_m,where t_r is the retention time and t_m is the time for mobile phase or unretained solutes to pass through the column. C)The relative retention,$\alpha$= ,is the ratio for the adjusted retention time for two components of the sample,where t_r2^' t_r1^' so that $\alpha$ 1. D)The retention factor,k = ,is the time,t_r,required to elute a component minus the time,t_m,for mobile phase to pass through the column divided by t_m. E)The relative retention,$\alpha$,also equals ,where K₂ and K₁ are the partition coefficients for components 2 and 1.
