TI  - Single-column method of ion chromatography for the determination of common 
      cations and some transition metals.
PG  - 68-72
AB  - A single-column method for the simultaneous determination of common cations and 
      transition metals in real samples is proposed in this paper. Eleven cations 
      (copper, lithium, sodium, ammonium, potassium, cobalt, nickel, magnesium, 
      calcium, strontium and zinc) were separated and analyzed by means of ion 
      chromatography using an isocratic elution with 2.5 mM methane sulfonic acid and 
      0.8 mM oxalic acid as mobile phase, IonPac SCS1 (250 mm x 4 mm I.D.) as the 
      separation column and non-suppressed conductor detection. Optimized analytical 
      conditions were further validated in terms of accuracy, precision and total 
      uncertainty and the results showed the reliability of the IC method. The relative 
      standard deviations (RSDs) of the retention time and peak area were less than 
      0.04 and 1.30%, respectively. The coefficients of determination for cations 
      ranged from 0.9988 to 1.000. The method developed was successfully applied to 
      determination of cations in samples of beer and bottled mineral water. The spiked 
      recoveries for the cations were 94-106%. The method was applied to beer and 
      beverage without interferences.
