TI  - On-line preconcentration system using mini-column packed with a chelating resin 
      for the characterization of seasonal variations of trace elements in seawater by 
      ICP-MS and ICP-AES.

AB  - An on-line column preconcentration technique coupled with inductively coupled 
      plasma-mass spectrometry (ICP-MS) and -atomic emission spectrometry (ICP-AES) was 
      developed using a mini-column (ca. 3 mm i.d., 40 mm length), that was packed with 
      chelating resin (0.2 g) of iminodiacetic acid groups, Muromac A-1. After the 
      preconcentration step, the column was washed with ammonium acetate buffer (pH 
      5.5) and water to remove major elements, such as Ca and Mg, and then eluted with 
      4 ml of 2 mol l(-1) nitric acid. Eleven trace elements (Al, V, Fe, Co, Ni, Cu, 
      Zn, Cd, Pb, Th and U) in seawater were determined by ICP-MS/AES. Recoveries for 
      most of the elements tested were over 90%, although those for Al, V and Th were 
      around 70%. The accuracy of the proposed method was evaluated by analyzing a 
      standard reference material of seawater (NASS-4, NRC Canada). The values of Fe, 
      Co, Ni, Cu, Zn, Cd and Pb obtained with the present method showed good agreement 
      with the certified values as judged from the standard deviation. The method was 
      successfully applied to characterize seasonal variations of trace elements in 
      deep seawater (DSW) and surface seawater (SSW). In addition, no serious decrease 
      in analytical performance of the present column system was observed during the 
      experimental period of about 1 year.
