Further considerations of exact equations for peak capacity in isocratic liquid chromatography.

Further consideration is made of the exact equation for peak capacity by Potts, L. W.; Carr, P. W. Anal. Chem. 2011, 83, 7614–7615 for liquid chromatographs with significant extra-column broadening. Equivalent exact equations are easily derived that provide comprehension and insight of how extra-column broadening degrades chromatographic performance as measured by peak capacity.
