Analytical laboratories gasoline age dating analysis

Analyses includes: Distillation and radiometric measurement of Tritium Analysis with Electrolytic Enrichment (TEE) Applications: Useful for tritium concentrations too low to be measured by direct counting. Analyses includes: Electrolytic enrichment and radiometric measurement of H concentration.

Stable Isotopes | Radiocarbon | Dissolved Gas | Nitrates | Sulfates Tritium Analysis of Groundwater Advantageous for age dating of groundwater and identifying water that is less than 40 years old, Isotech offers several different types of analyses that can be used to evaluate tritium concentrations in landfill leachates (some leachates have tritium concentrations of several thousand TU).The laboratory is located in the USGS Headquarters in Reston, Virginia.Made analytical methods for document dating Post sent to administrative law judge and associate analysis age director.This prevents contamination of our electrolysis cells with "hot" samples and means that you do not have to pay for electrolytical enrichment unless it is necessary. Stable Isotopes | Tritium | Dissolved Gas | Nitrates | Sulfates Radiocarbon Analysis of Groundwater (RAG) Applications: Useful for age dating of groundwater and for identifying influence of landfill gas and leachate on groundwater.Identifies up to 149 compounds in the range between gasoline and residual oil. Assists in identification of types of free product or crude oils present.

Degree of degradation provides information on the age of a product.

The data generated by the Groundwater Dating Laboratory are being used throughout the USGS in hydrologic studies.

The lab's staff work together in research to refine the use of groundwater dating techniques and to develop new groundwater dating methods.

For pricing, please see the Services & Pricing page. The Dissolved and Noble Gas Lab primarily carries out groundwater age dating by measuring the concentrations of helium-3 (H), a radioactive isotope of hydrogen.

Atmospheric atomic bomb testing in the 1950's and 60's bolstered the concentration of tritium in the atmosphere where it can become incorporated into a water molecule and enter the water cycle.

Age dating will allow an approximate range of as to when the release occurred.
