C. Horvath C. Horvath graduated as a chemical engineer from the Technical University of Budapest in 1952 and became a faculty member in the Organic Chemical Technology Department until 1956 when he transferred to Germany. From 1956 to 1961 he worked in German industry and then studied at the University of Frankfurt am Main and obtained his doctorate in 1963. He then moved to America and became a research fellow at Harvard Medical School and in 1964 became an associate professor in the Engineering Department at Yale University. C. Horvath made many significant contributions to both gas chromatography and liquid chromatography and has extended his interests to biotechnology. He has published over a hundred technical papers and written or contributed to a number of books. He has also received numerous awards for his work in both gas and liquid chromatography.

;          0                 0                  97.30                        Furthermore, for the Huber equation, the value of coefficient (E) is consistently zero and for the Horvath equation, is zero for four solvents mixtures out of six, with an extreme value of 97.3 for one solvent. On the basis of the irrational fits of the data to the Huber and Horvath equations, these equations will not be considered to satisfactorily describe the relationship between (H) and (u). According to Katz et al.  the same irrational behavior of the Huber and Horvath equation was observed if the data for hexamethylbenzene was also fitted to them

The Horvath and Lin Equation In (1976) Horvath and Lin (23) introduced yet another equation to describe the value of (H) as a function of the linear mobile phase velocity (u). Their equation is given as follows,                                           (51) The equation of Horvath and Lin

Unfortunately, this is of little use as, due to their nature, all five equations would provide an excellent fit to any given experimentally derived data set, provided the data was obtained with sufficient precision. However, all the individual terms in each equation purport to describe a
