  • A technique for separating ion mixtures

 

    • Chromatography column separates ion mixture
    • Detector measures conductivity
      • More ions = bigger conductivity signal
    • Chromatogram is plot of conductivity vs. time
      • Peak time gives identity
      • Peak area give concentration

                

    • Standard curve converts peak area(uS*min) to concentration (M)
