Vn. Epov et al., Determination of trace elements in Baikal water by inductively coupled plasma mass spectrometry, J ANALYT CH, 54(11), 1999, pp. 1034-1039
An analytical scheme was developed for determining trace elements in water
with ultralow mineralization using inductively coupled plasma mass spectrom
etry in combination with the method of single- and multielement standard ad
ditions. The conditions of instrumental analysis were described. Groups of
trace elements that can be determined by the method of single- and multiele
ment additions (concentrations 0.05-100 mu g/kg) calculated on the basis of
element distribution in the studied water were recommended; the additions
were introduced by gravimetry. Internal standards for the analyte isotopes
used to calculate concentrations were selected, and correlation equations w
ere derived. Performance characteristics of the results of analyses were es
timated.
