Mercury (Hg) research requires many specialized protocols and Standard Operating Procedures (SOP). Our mercury methods have been outlined in various Quality Assurance Protection Plans (QAPP). All our procedures are rigorously followed and tested to maintain maximum Quality Assurance (QA) and Quality Control (QC). We often conduct inter-lab comparisons with other labs that regularly do Hg analysis to ensure our methods are consistent, accurate and up-to-date (results available upon request).
Our lab has been cleanly collecting and analyzing ambient-level Hg samples from the environment since in the 1980's. This lab was at the fore-front of methods that have since been adopted as EPA Standard Methods 1631 and 1669 for the collection and analysis of HgT. Hopefully, there should be a Standard Method for MeHg Analysis soon. Because of our research and development-based focus we continue to strive on our methods. We use both Tekran and Brooks-Rand Hg detectors. Please contact us for further information.
Some methods below are specific to mercury and others we consider ancillary, but very important and necessary for the full interpretation of the data that we collect. For an overview, the Total and Methyl Mercury Analysis SOP's are a good place to start. They include methods for the analysis of both aqueous and solid phase samples.
