Frequently Asked Questions on Lead Isotopic Ratios

1. Are you able to measure Lead 210?

No, we do not currently offer Lead 210. At this time we offer precise measurements for 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb, 208Pb/206Pb, and 207Pb/206Pb ratios. Learn more about the lead isotopes we currently measure. 

2. Can zircon material be submitted for dating?

While this material can be submitted for isotopic analysis, we do not provide any chronology services through our lead analysis.

3. What precision does Pb yield?

The lead isotope method uncertainty of NIST SRM 981 standard solution varied from ±0.000047 to  ±0.000023 (%95 CI) for 207Pb/206Pb .
