- Abstract
- A method, based on inductively coupled plasma sector
field mass spectrometry coupled with a microflow nebulizer
and a desolvation system, has been developed for
the direct determination of rare earth elements (REE) (La,
Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu) down
to the subpicogram per gram level (1 pg/g ) 10-12 g g-1)
in ~1 mL of molten Antarctic ice. Contamination problems
were carefully taken into account by adopting ultraclean
procedures during the sample pretreatment phases.
The use of a desolvation system for sample introduction
during the analysis greatly reduced spectral interferences
from oxide formation; the residual interfering contributions
were calculated and subtracted whenever necessary.
A matched calibration curve method was used for the
quantification of the analytes. Instrumental detection
limits ranged from 0.001 pg/g for Ho, Tm, and Lu to 0.03
pg/g for Gd. The precision, in terms of relative standard
deviation on 10 replicates, ranged from 2% for La, Ce,
Pr, and Lu, up to 10% for Er, Tm, and Yb. This methodology
allowed the direct determination of REE in a 1-mL
sample of ancient Antarctic ice with concentration ranges
between 0.006 and 0.4 pg/g for Tm and 0.9-60 pg/g
for Ce. (literal)
