The Environmental Isotope Laboratory offers one of the most complete arrays of analytical services of any laboratory in the US.

Message about Turnaround times (last updated August 14, 2014)

Tritium: currently ~ 3 months

O, H stable isotopes in water: currently ~ 2 weeks

14C dating: The Radiocarbon Lab has closed. Please contact the NSF-Arizona Accelerator facility for radiocarbon dating services.

S isotopes: next runs are in May 2015 and September 2015. Please get samples for the May run to us by May 15.

 

Radiocarbon Dating by Liquid Scintillation Counting. See message above.


Tritium Analysis in Water Samples $196

  • Detection limit 0.6 TU, or 1.6 pCi/L for 9X enrichment
  • Turn-around time, contact us


Stable Isotope Measurement

University of Arizona researchers receive discounted rates for some analyses. Please contact David Dettman for our internal UA rate sheet.

Helpful Hints

  1. Simple sample identification systems (e.g.   AB-1, AB-2…..) save us time, and reduce the likelihood of errors.  
  2. For large sample sets, please send by e-mail an Excel spreadsheet listing the samples in a logical order.
  3. Prices quoted do not include extra sample preparation such as drying, powdering, separating from filters, carbonate removal.
  4. Please tell us if we are handling hazardous samples.
     

Sample Storage Policy

Unless we make another arrangement at client request, we will retain leftover sample materials for one year, then dispose of them.

Payment Methods

  • Please submit samples with an institutional "Purchase Order" if possible.
  • Wire Transfers must include a $20 processing fee.
  • * Cash, check, and wire transfer payments receive a 3% discount.
