Bio-Rad Bio-Beads S-X Media - Manual (Page 15)

Bio-Beads S-X2 and S-X8 beads have been used in multi-
column system for separating various components of tall oil,
wood resin, and gum resin by gel permeation chromatography.

Figure 2 shows the fractionation of tall oil with Bio-Beads S-X
beads. All of the injected acid sample was fully recovered, and
no delay in elution time was noticed.
