AN94: Determination of Trace Cations in Concentrated Acids (Phosphoric Acid) Using AutoNeutralization Pretreatment and Ion Chromatography
Description
The determination of trace cationic contamination in processing acids (phosphoric, sulfuric, hydrofluoric) is important to the electronics industries to minimize corrosion. Here trace cationic contamination is determined in a 25% phosphoric acid sample. The acid sample is automatically neutralized through an electrolytic device, and then retained and concentrated onto a concentrator column. After eluting from the concentrator column, the µg/L cations are determined on an IonPac CS16 column using electrolytically generated MSA eluent and suppressed conductivity detection.| Market: | Chemical |
