 Related applications:
Industrial Chromatography
Separate multivalent and polarizable anions in 25 minutes without solvents using the Thermo Scientific™ Dionex™ IonPac™  AS25 column. This high-capacity, hydroxide-selective, anion-exchange column is ideal for the determination of sulfur species in complex matrices such as food and beverage samples as well as wastewater effluents from the industrial, chemical, and petrochemical industries. This column delivers fast, simple separation of polarizable anions, including thiosulfate, iodide, thiocyanate, and perchlorate. For the best peak shape of polarizable anions, use the Thermo Scientific™ Dionex™ IonPac™ AS16 column or the Thermo Scientific™ Dionex™ IonPac AS20 column.
