*Ten sample minimum charge (due to number of references needed for analysis)


**The highest enriched reference water being maintained has isotope values of 1690 δD per mil or 0.042 at% D and 263 δ18O per mil or 0.25 at% 18O. Please contact us regarding enriched water expected to exceed the current range of enriched laboratory reference material.

 

The SIF does not analyze samples with a pH below 5 or above 9.


If your water samples are likely to contain a significant amount of organics (e.g. metabolic waters, plant/soil extracts, etc.), please contact us before submitting samples. Any waters registering a contamination will be flagged in the reported data.

 

Waters containing ≥30 mS/cm, or saline waters at salinity greater than 20, are considered sufficiently impacted to incur the higher rate. Waters depositing significant salts in the system could also be charge the higher rate.
