The value of StR with tRmea on thirty columns was used to in shape a number of level linear equation. The averages of ΔtR (average ± standard deviation) were calculated, as revealed in Fig. three. For both medicines, the prediction deviation was minimized with raising quantity of columns. On the other hand, the prediction precision will not be substantially improved when the volume of columns reaches 5, that is considered as a low-Charge and reasonable Restrict. It is usually recommended to select five–fifteen columns for StR calculation.
