The stationary phase of superheated water chromatography must be stable against the attack of water. A durability test for PSDVB packings and octadecylsilyl (ODS)-silica gels indicated that PSDVB packings were stable in superheated water in the temperature range of 100 - 150°C, whereas octadecylsilyl groups of ODS-silica gels cleaved even at 100°C. The retention of phenols on the PSDVB stationary phase decreased with an elevation of the column temperature. The retention mechanism was characterized using a thermodynamic theory that has been used for describing retention in conventional RP-HPLC. The application of the present method to an environmental analysis was also demonstrated, in which a suitable separation with good peak shape was obtained for p-chlorophenol in river-water samples., text, application/pdf}, pages = {269--272}, title = {Superheated water chromatography of phenols using poly(styrene-divinylbenzene) packings as a stationary phase}, volume = {19}, year = {2003}, yomi = {シブカワ, マサミ} }
