Recent scientific articles published by many of the most popular authors in HPLC, based both in Academia, as well as at industry leading companies, regarding the relatively new technology in chromatography known as UHPLC, have increasingly focused on a methodology of evaluating the performance of packed chromatographic columns, by suggesting that the value of the Kozeny constant is variable, rather than a constant. This practice is totally invalid and, in addition, is demonstrably false. In this paper, we will prove, conclusively, that this is the case. In so doing, we will use the experimental data provided by these very authors themselves, in combination with well – settled fluid dynamics theory dating back to 1901, to prove that their conclusions relative to their calculated values for the Kozeny constant, are entirely without merit and not supported by their own measurements. In addition, we will further demonstrate that, based upon a newly minted theory of fluid dynamics in closed conduits, published for the first time in 2019, representing the most recently published reference in fluid dynamics, the unique constant value for this Kozeny parameter, which has been previously shown to be validated over the entire fluid flow regime, will be identified and applied to the reported data, thus, correcting for the errors made by the paper authors and ending approximately 150 years of ambiguity in the science of packed conduits and, HPLC, in particular.
