✦ Synopsis

The fat-soluble vitamins retinyl palm&ate, D,, E and K, were separated on a packed reversed-phase fused-silica capillary column using methanol-tetrahydrofran as mobile phase, and determined with UV detection. Conventional liquid chromatographic equipment was adapted for such purposes, providing a highly efficient and sensitive analytical system. The vitamins could be separated isocratically with detection limits of 2.9 pg, 1 pg, 29 pg and 2.6 pg, respectively. Application of the proposed method to the quantification of fat-soluble vitamins in blood is reported.
