DIONEX ICS3000 ION CHROMATOGRAPHY SYSTEM INSTALLATION AND INSTRUMENT ASSESSMENT FOR SRNL APPLICATIONS
Ion Chromatography (IC) is routinely used at the Savannah River National Laboratory (SRNL) for sample analysis and characterization. Results from IC analysis are valued in corrosion control maintenance and measurement programs, remediation waste process control, soil and ground water measurement, nuclear materials processing, and various other research and development programs. Presented in this report are analytical methods developed on a DIONEX ICS3000 Reagent Free Ion Chromatography (RFIC) system located in AD at SRNL. This IC system contains two independent analysis channels comprising of a mobile phase generator, a pump, stationary phase columns, a suppressor and a conductivity detector. One channel is dedicated to anion analysis using Potassium Hydroxide (KOH) as the mobile phase while a second channel is configured for cation analysis using Methanesulfonic Acid (MSA) as the mobile phase. Both channels share an autosampler and the peak analysis software, Chromeleon{reg_sign} v.6.8. Instrument configuration is modified from the manufacturer for radiological service. Listed within this report are Dionex ICS3000 parameters and results for the analysis of routine anions and cations. Additional method parameters and discussion are presented on the analysis of Acetate (CH{sub 3}COO{sup -}) and Iodate (IO{sub 3}{sup -}). Previous IC analysis instruments at AD have been based upon carbonate/bicarbonate buffer mobile phase chemistry. This report represents a transition to hydroxide as a mobile phase eluent. The hydroxide eluent offers a lower baseline conductivity, which allows for greater sample dilution and/or lower detection limits. Also the hydroxide mobile phase and column set has a significant separation of the phosphate peak from the nitrate and sulfate peaks vs. the carbonate/bicarbonate mobile phase and column set, an advantage for the industrial waste analyzed at SRNL.
