High molar mass birch lignosulfonates

Figure 2. Fractionation of high molar mass birch lignosulfonates (fraction A in Figure 1) by preparative reversed-phase chromatography.

It was shown that high molar mass lignosulfonate compounds can be fractionated by RPC into hydrophilic and hydrophobic compounds. It can be seen from Figures 4 and 5 that the birch lignosulfonates with low molar mass (fractions B and C in Figure 1) were also fractionated into hydrophilic and hydrophobic portions with no clearly resolved peaks.
