With over 1300 commercial testing labs in the United States, one out of every three samples is for water analysis. There has been an even stronger emphasis on mercury testing and its concentration in our water supplies. This application note describes the use of cold vapor atomic absorption spectroscopy as described in the EPA method 245.1 to determine mercury concentration in water samples including drinking, surface, ground, sea, brackish waters, and industrial and domestic waste waters.
Determine mercury concentrations in surface water samples. In addition to the water samples, pre and post QC checks (15 ppt standards) served to ensure instrument stability and accurate results.Principle of Operation
Discussion and Conclusion
The Mercurio AAMA-80 successfully recovered 100% of the 15 ppt Hg standards and processed 10 surface water samples with excellent reproducibility and accuracy without any interference.
