title: Tissue porphyrin pattern determination by high-speed high-performance liquid chromatography.
abstract: A rapid and sensitive method for the determination of porphyrin carboxylic acids in liver, kidney, and spleen by high-speed high-performance liquid chromatography is described. Porphyrins were extracted with recoveries greater than or equal to 98%, concentrated on disposable octadecylsilyl cartridges, and analyzed with a liquid chromatograph equipped with a 3 microns X 3 cm octadecylsilyl column and a fluorescence detector. Separation of di-, tetra-, penta-, hexa-, hepta-, and octacarboxylic acids was achieved within 5 min. The detection limits for uro, copro, and protoporphyrin were 20, 10, and 20 fmol, respectively.
