Determination of lead isotope ratios in environmental matrices by quadrupole ICP-MS working at low sample consumption rates
Measurement of lead isotope ratios in environmental matrices using inductively coupled plasma-dynamic reaction cell-mass spectrometry at low sample consumption rates was investigated. Two micro-sample introduction systems were evaluated, namely the PFA micronebuliser associated with a low-volume spr...

Measurement of lead isotope ratios in environmental matrices using inductively coupled plasma-dynamic reaction cell-mass spectrometry at low sample consumption rates was investigated. Two micro-sample introduction systems were evaluated, namely the PFA micronebuliser associated with a low-volume spray chamber, working at 150 mL min?1 and the total-consumption sample introduction system TISIS, operating at 20 mL min?1. In both cases, the dynamic reaction cell pressurised with ammonia was applied to improve the precision by collisional damping. Under optimal operating conditions, 208Pb/207Pb and 206Pb/207Pb ratios were accurately determined with an internal precision of 0.12–0.13% and 0.17–0.18% (%RSD, n ¼ 10, c ¼ 10 mgL?1; t ¼ 10 s). The sample consumption for the assessed sample introduction systems was less than 1.5 mL and 200 mL, allowing the precise analysis of limited-size samples and pre- concentrates.
