A dual-flame photometric detector was modified to be used in a capillary supercritical fluid chromatographic system. The detection limit was found to be 25 ng for the sulfur mode and 0.5 ng for the phosphorus mode when supercritical carbon dioxide was used as the mobile phase. The advantages and limitations are discussed and demonstrated with several applications. 18 references, 6 figures.
