Stuff I'm working on and such.

Laboratory details

Uranium-lead dating relies on measuring the isotopic composition of both elements, which is accomplished using an isotope ratio mass spectrometer. In thermal ionization mass spectrometry (TIMS) U-Pb dating, a solution with a known ratio of synthetic ²⁰⁵Pb and ²³³U isotopes is added, a process known as isotope dilution. This allows measurement of the natural isotopes in relation to the synthetic ones. From the known synthetic Pb/U ratio, the ²⁰⁶Pb/²³⁸U and ²⁰⁷Pb/²³⁵U ratios in the sample can be determined.
