TIC (a) and EIC profiles (b-f) of prevalent structural families found in PPS by IPRP-HPLC/ESI-ICRFT-MS (a) – TIC, (b) – EIC of Xyl_nS_2n+1 structures (n: 1-15), (c) – EIC of Xyl_nS_2n-H₂O structures (n: 2-14), (d) – EIC of Xyl_nMGA₁S_2n+2 structures (n: 1-12), (e) – EIC of Xyl_nMGA₁S_2n+1Ac₁ structures (n: 3-13), (f) – EIC of Xyl_nS_2n+1Py₁ structures (n: 2-14)

m/z values used for obtaining EIC profiles are those of the most abundant ion form reported in Table 6 Xyl – xylose repeating unit, MGA – branching 4-O-methyl-glucuronic acid, S – sulfate group, Ac – acetyl group, Py – pyridine moiety, # - salt clusters
