Trace Elements Speciation

Brooks Applied Labs has developed an array of analytical techniques for trace metals speciation depending on the sample matrix and target molecules. Due to the unique chemical properties of different trace metals molecules one analytical method will not work for all species and all sample matrices. Through in-house research and method development and collaborations with industry scientists at BAL have generated robust preparatory and analytical methods to support most trace metals speciation
Arsenic Speciation (As)

The experience of Brooks Applied Labs comes into play when arsenic speciation in difficult matrices is to be determined. We have developed a variety of different arsenic testing methods that utilize different chromatographic separation modes. These methods allow us to provide the lowest detection limits to our clients for their toughest samples. For instance, arsenic speciation in a 10,000 ppm Fe, Ca, Al and high sulfate matrix or highly saline...
Chromium Speciation (Cr)

Chromium (Cr) is a polyvalent element and can exist in several distinct oxidation states, but only trivalent chromium [Cr(III)] and hexavalent chromium [Cr(VI)] occur with any frequency in the natural environment. The mobility, bioavailability, and toxicity of chromium largely depend on which of these two chemical species is prevalent. The speciation of chromium is determined by the processes that control reduction/oxidation reactions in the...
