This thesis is divided into four parts. In the first part, the history of chromatography is described. Different modes of chromatography are briefly discussed and a survey of stationary phases being used in High Performance Liquid Chromatography (HPLC) is made. The need for a non-polar reversed-phase stationary phase is highlighted. A brief survey of the use of carbon by other workers in liquid chromatography is also made. The second part of the thesis deals with the production and structural study of porous graphitic carbon (PGC). the different stages of production of PGC are discussed. Pore volume and surface area studies on PGC have also been made. A detailed structural study of PGC has been presented. The third part of the thesis deals with the literature survey of the formation of surface complexes on carbon and the gas reactions of carbon, an understanding of which was necessary for the production and control of the final quality of PGC. The fourth part of the thesis deals with the use of PGC in HPLC. A packing method for PGC has been investigated. Different batches of PGC's produced have been tested with standard test solutes. A separation of a wide variety of solutes, including polymethylphenols, polymethylbenzenes, alkylbenzenes, bases, acids, polyaromatic hydrocarbons, pheynl ketones and phthalates on PGC have been achieved. Analgesics can also be separated. Solvent strengths on PGC have been investigated using different solvents and different solutes.
