ANSWER
K' (K prime, or capacity factor) in chromatography is used to help assess if a peak is going to give reproducible and linear results over time. This ensures that small errors in mobile phase or pH do not have a large impact on retention time or response of the peak. In addition, the factor shows that the peak is moved sufficiently from the void to keep it away from other compounds that may elute in the void of the column and interfere with the response.
