AU133: Saccharin in Electrolytic Nickel Sulfate Baths
Instrument Type: ICSaccharin decreases the tensile strength of electrolytic nickel deposits and can, with increasing concentrations, cause compressive stress. Determination of saccharin by ion chromatography is faster and has fewer interferences than classical titrimetric methods of analysis.
AN94: Determination of Trace Cations in Concentrated Acids (Sulfuric Acid) Using AutoNeutralization Pretreatment and Ion Chromatography
Instrument Type: ICThe 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 24% sulfuric 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.
