NanoPak-C All-Carbon capillary HPLC columns offer porous graphitic carbon selectivity for glycans, glycopeptides, PTM-rich peptides, and polar metabolites in nanoLC–MS proteomics workflows. In an independent head-to-head comparison with commercial PGC and C18, NanoPak-C showed sharper peaks, faster column stabilization, and a cleaner MS baseline.
