Analyses & Rates

Last Updated: July 2021

The Stable isotope laboratory provides high-quality analyses on numerous substrates for on-campus, off-campus, and commercial users. Please contact Dr. Linda Reynard regarding research projects and analytical needs.

[1] Isotopically enriched samples must be identified prior to submission for analysis!

[2] Prices include standardization.

[3] Waters with dissolved organics or salts must be identified prior to submission for analysis and will incur additional cost.

[4] Prices include %C and %N for organics.

[5] Please contact us before weighing/encapsulating your own samples.

[6] Includes cost of grinding and weighing.

[7] Commercial samples are analyzed with cost multipliers of the on-campus rate:

  • 3.5 for <100 samples
  • 2.75 for 100-500 samples
  • 2.0 for >500 samples.
