AU72331: In-line Sample Preparation for the Determination of Anions in Sodium HydroxideInstrument Type: IC
Determination of anions in high pH samples is important for a variety of industries. But anions in a high pH sample cannot be determined without proper sample pretreatment due to the high concentration of hydroxide, which can act as an eluent, in the sample. This record shows an easier method to determine mg/L concentration of anions in sodium hydroxide using automated inline sample preparation with Thermo Scientific™ Dionex™ Guardcap™ H vial caps. The caps serve as a cation exchange cartridge to neutralize samples before loading to the Thermo Scientific™ Dionex™ IonPac AS23-4μm column.
