Noise identification and sampling frequency determination for precise Pb isotopic measurements by quadrupole-based Inductively Coupled Plasma Mass Sp…
2000
Analytical precision of the isotope ratios measured by quadrupole-based ICP-MS is drastically controlled by the low- frequency noises which originate from nebulisation and vaporisation processes, and from sample introduction systems. The unde- sirable influence of these latter can be however reduced by choosing efficiently the operating parameters. In the present study , the choice of the stabilisation time necessary in peak jump mode, and the one of the number of sweeps are discussed in the light of noise power spectra obtained with various speeds of the peristaltic pump used as sample introduction system. Obviously, the settings proposed are probably efficient only on our own ICP-MS, but …
