Ion exchange columns for special applications

These Thermo Scientific™ IonPac™ columns were designed for special applications such as for non-suppressible eluents in combination with a variety of detection modes, including amperometric and UV-Vis detection. They are useful for separations of higher-valence anions and transition metals.

Specialty anion-exchange IC columns


Recommended Use

Target Applications

Dionex™ IonPac™ AS7 IC Columns Separation of a wide variety of polyvalent anions, including polyphosphates, polyphosphonates, EDTA and NTA. Method uses postcolumn derivatization and UV-Vis detection Analysis of polyvalent anions and chelating agents in complex sample matrices, hexavalent chromium in environmental matrices, cyanide and sulfide using amperometric detection.
Dionex™ IonPac™ AS5 IC Columns Separation of higher-valence anions including polyphosphates, oxyanions, EDTA complexes, metal cyanide complexes, and hydrophobic anions such as iodide, thiosulfate, and thiocyanate; Dionex IonPac AS16 or AS20 columns recommended for hydrophobic anions and highly-charged anions. Separations of higher-valence and hydrophobic anions, and rapid elution of strongly retained species such as iodide and thiocyanate in brines without interference from the large chloride peak typical of such samples.
Dionex™ IonPac™ CS5A IC Columns Accurate simultaneous determination of common transition and lanthanide metals; high-sensitivity and selectivity in combination with postcolumn derivatization and visible detection at 530 nm; also used for aluminum analysis.  Analysis of transition and lanthanide metals in a variety of sample matrices including high-purity water, plating bath solutions, and power industry waters.
