The experimental results are represented in Figure 1 ; as in ref. [5], the log k'and Csaxes have opposite directions. Although only few values of solubility are available, the variations of log kvalues and log CS values of 2-hydroxynaphthalenc? are clearly seen to be parallel; some deviations are

Over the last decade, monoliths or continuous beds have emerged as an alternative to traditional packed-bed columns for use in capillary electrochromatography (CEC) and micro-high performance liquid chromatography (micro-HPLC). Monolithic columns can be divided into two categories: silica-based mono
