Silica-based anion exchangers are available from a number of manufacturers. Typical trade names include Vydac (Separations Group, Hesperia, CA, U.S.A.), Wescan (Alltech, Deerfield, IL, U.S.A.), TSK Gel (Toyo Soda, Tokyo, Japan) and Nucleosil... [Pg.51]

Figure 3.82 shows a typical example of an inorganic anion separation on a silica-based ion exchanger, Vydac 302 IC 4.6. For comparison. Figure 3.83 shows a similar separation on Nucleosil 10 Anion. In this chromatogram, orthophosphate elutes first, because it is a monovalent ion due to the comparatively low pH value of the mobile phase. [Pg.127]
