About the Lab
This Keck Lab was established with the intent to get scientists
directly involved in all aspects of isotope ratio measurements. Far
too often scientists accept results from external labs without the
ability to evaluate the data quality for themselves. Additionally,
direct knowledge of the analytical technique gives individuals a
better idea of how to improve their sampling technique and how to
incorporate other analyses into their research.
Research groups interested in using these facilities need to provide at least one person who will be trained to prepare and set up samples for analysis. This same person will be responsible for programming their sample sequence, carrying out the analysis,
and will also process the results to get the final numbers. This is
particularly important as it makes clear the role of the working
standards, linearity checks, and estimations of analytical uncertainty. All of this will be supervised and all
results obtained in the lab must be checked and approved (signed off) by the lab
manager to ensure data quality.
There is still room for analyses for groups that only have a small
number of samples to run. If you have special applications or
interests, or only a couple of samples to run, please contact the lab
The director of the Keck Lab is
Dr. Gwyneth Gordon, manages all aspects of clean lab, general lab,
and ICP use. Aside from her own work on the
instruments she also provides training, maintenance and method
development on the ICP instruments. All questions related to ICP
analysis should be addressed to Dr. Gordon. Click
to contact her.
Dr. Anthony Michaud, was involved in the setup of the
gas IRMS instruments, method development, webpage management, and
laboratory infrastructure for the first three years of the lab. He
left ASU on June 30th to pursue a different path at UC Davis school of
medicine. May he find plenty of wind and water wherever he ends up!
