的詳細介紹
IonPac AS5 Specialty Anion-Exchange Column
For Separating Higher-Valence Anions
The IonPac? AS5 separates higher-valence anions, including polyphosphates,
oxyanions, EDTA complexes, metal cyanide complexes, and hydrophobic
anions such as iodide, thiosulfate, and thiocyanate.
-
For metal-EDTA complexes
-
For cyano-transition metal complexes
-
For hydrophobic anions, including iodide, thiocyanate, and thiosulfate
-
AS16 or AS20 columns are recommended for hydrophobic anions and highly charged anions
The
AS5’s compatibility with weak eluents simplifies the determination of
strongly-retained species, since these eluents are compatible with a
suppressor. Furthermore, the rapid elution of strongly-retained species
greatly improves peak shapes, lowers minimum detection limits, and
increases sample throughput potential.
The selectivity of the AS5
makes it possible to rapidly elute strongly-retained species such a
iodide and thiocyanate in brines without interference from the large
chloride peak typical of such samples.
Note: IonPac AS16 or AS20 columns are recommended for hydrophobic anions and highly-charged anions.
