IC-pak Column and guard Column
I. IntroduCtIon
Waters IC-Pak™ anion (A) and cation (C) columns are designed for use
in Ion Chromatography (IC) applications to separate ions.
a. Anion Columns
The stainless steel anion columns separate and quantify many
anions, such as F

anions at
ppb levels. Table 1 lists the characteristics of IC-Pak anion columns.
Table 1: Anion Column Characteristics
The packing material is a polymethacrylate resin with a quaternary
ammonium functional group. The columns are shipped in 1.3 mM
gluconic acid/1.3 mM boric acid (pH 8.5).
b. Cation Columns
The non-metallic cation columns separate and quantify Li

cations at ppb levels. The Waters
cation guard column, placed in the solvent stream before the
sample injector, is used only to aid monovalent cation detection by
removing polyvalent cations from the solvent stream.
Table 2 lists the characteristics of IC-Pak cation and cation guard
columns.
