Water Analyses


Tritium Analysis via Scintillation Counter

Applications: Water dating, nuclear event studies and landfill studies

Direct Count

Analysis is effective when elevated tritium concentrations are expected such as landfill and nuclear event studies. The quantifiable limit for direct count is 10-15 TU based on the specific statistics of the run. Smaller concentrations will be reported as a less than value based on the statistics.

Sample size: We recommend sending in 50 mL of water. Analyses on smaller amounts are possible. If you wish to analyze less than 10 mL please contact us first.

Sample Container: We recommend a HDPE (plastic) bottle.

Preservative: No preservative or cooling is required. Ensure that the bottle is air tight to prevent evaporation.

Holding time: Samples should be sent in within six months of sampling.

Shipping: No special considerations are needed in shipping these samples. Please inculde a COC.

Electrolytic Enrichment:

For tritium levels below modern levels electrolytic enrichment is suggested. The quantifiable limit for electrolytic enrichment is 1TU. Smaller concentrations will be reported as a less than value based on the statistics.

Sample size: We recommend sending 1 liter of water. Analysis on smaller amounts is possible. If you wish to analyze less than 500 mL please contact us first.

Sample Container: We recommend a 1 liter HDPE (plastic) bottle.

Preservative: No preservative or cooling is required. Ensure that the bottle is air tight to prevent evaporation.

Holding time: Samples should be sent in within six months of sampling.

Shipping: No special considerations are needed in shipping these samples. Please inculde a COC.
