title: On-line high-performance liquid affinity chromatography-high-performance liquid chromatography analysis of monomeric ribonucleoside compounds in biological fluids.
abstract: We describe an on-line multi-dimensional column chromatography system. It consists of a high-performance liquid affinity chromatography perfractionation column for cis-diol compounds and a series-connected reversed-phase high-performance liquid chromatography system for the analysis of ribonucleosides. This on-line procedure allows the rapid and direct analysis of methylated ribonucleic acid catabolites in biological fluids (serum, urine) and therefore might be useful in pathobiochemistry.
