Metals Testing and Metals Speciation
Trace metals can be further differentiated from their total elemental composition into different redox species, organometallic compounds, complexes, or precipitates/minerals. This differentiation is the basis of metal speciation. Each species of a specific element has different chemical and physical properties sometimes with profound differences in mobility, bioavailability, and/or toxicity. Investigating the speciation of metals can provide valuable information on the toxicity and mobility of the trace metals to living organisms and troubleshooting metals removal from systems such as water treatment.
While analytical techniques for trace metals speciation have been around for over a decade, few laboratories possess the expertise to apply these techniques for various commercial applications. Eurofins Frontier Global Sciences has been providing elemental speciation analytical services since 1991 and has continued to create and implement several unique tools and applications for our clients.
Eurofins Frontier Global Sciences offers speciation in a variety of matrices using the following methods and techniques:
- EPA 1632 As Speciation (As3/As5)
- EPA 1630 Methyl Mercury
- EPA 1630Mod DiMethyl Mercury
- EPA 1631Mod Elemental Mercury
- EPA 1631Mod Inorganic Mercury
- EPA 1631Mod Hg Selective Sequential Extraction (F0-F6)
- EPA 7196 Hexavalent Chromium in Water
- SM3500-Cr Hexavalent Chromium in Water
- Other speciation via LC-ICPMS or LC-AFS including Se, As, V, Mo, Co
