  • abstract:

    To precisely determine the abundances of fifty-two elements found within natural water samples, with mass fractions down to fg g-1 level, we have developed a method which combines freeze-drying pre-concentration (FDC) and isotope dilution internal standardisation (ID-IS). By sublimation of H2O, the sample solution was reduced to < 1/50 of the original volume. To determine element abundance with accuracy better than 10%, we found that for solutions being analysed by mass spectrometry the HNO3 concentration should be > 0.3 mol l-1 to avoid hydrolysis. Matrix-affected signal suppression was not significant for the solutions with NaCl concentrations lower than 0.2 cg g-1 and 0.1 cg g-1 for quadrupole ICP-MS and sector field ICP-MS, respectively. The recovery yields of elements after FDC were 97-105%. The detection limits for the sample solutions prepared by FDC were ≤10 pg g-1, except for Na, K and Ca. Blanks prepared using FDC were at pg-1 level, except for eleven elements (Na, Mg, Al, P, Ca, Mn, Fe, Co, Ni, Cu and Zn). The abundances of fifty-two elements in bottled drinking water were determined from five different geological sources with mass fractions ranging from the fg g-1 to µg g-1 level with high accuracy.

  • summary:

    Our results indicate that the FDC ID-IS method is an appropriate technique to determine extremely low trace element abundances accurately and precisely for natural water samples.
