IonPac AS5 阴离子交换色谱柱 The IonPac AS5 是一款低容量，氢氧化物选择性阴离子交换色谱柱。用于分离更高价态的阴离子，包括多磷酸盐，含氧阴离子，EDTA复杂物，金属氰化物，疏水性阴离子，如碘化物，留待硫酸盐，和硫氰酸盐。 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 stronly-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.
