Reliable ribonucleoside separation is achieved by reversed-phase chromatography using porous graphitic carbon (PGC) and C18 materials. (A) Representative chromatograms (A₂₅₄-trace) obtained with PGC-A (left panel), PGC-B (middle panel), and C18 (right panel) separating 20 ribonucleoside standards (LSM, Supplemental Table 1). (B) Individual chromatograms obtained for each of the 20 ribonucleosides included in the LSM using run conditions as in A. Abbreviations follow the Modomics database convention (Boccaletto et al. 2018).
