ICP-MS

Inductively Coupled Plasma Mass Spectrometry
Price on request

Inductively coupled plasma – mass spectrometry (ICP-MS) is widely recognized as one of the most accurate and precise analytical techniques for the determination of many trace elements in a wide variety of sample types. However, analyses using a conventional instrument configuration have also been persistently challenging due to spectral interferences that can severely compromise the accuracy of reported results.

 

Brooks Applied Labs supports trace elements quantification using both promulgated and internally generated methods depending on the data objectives and administrative requirements of the project. We use state of the art, inductively coupled plasma mass spectrometry with various interference removal technologies, to accurately determine arsenic, selenium, iron, chromium and various other elements with previously unattainable detection limits. Current interference removal technologies supported at Brooks Applied Labs includes: dynamic reaction cell (DRC), collision reaction cell (CRC), and triple quadrupole (QQQ). The availability of the different technologies allows us to choose the most appropriate approach to support the quality and data objective of nearly any project.

 

Conventional ICP-MS are prone to interferences from the matrix components that form polyatomic species in the plasma. Interference removal technologies are designed to reduce interferences and overcome many of these limitations. The end result is the elimination of false-positives and lowest detection limits for the toughest matrices.

Trace Metal Analysis

Price on request

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 requests.

New analytical techniques are generated and validated every month in accordance with industry demand as well as ecological and toxicological importance. Trace metals speciation analysis is currently supported for most sample matrices.

 

BAL currently has proprietary methods that support speciations of the following metals: 

 

- Arsenic Speciation Analysis
- Selenium Speciation Analysis
- Chromium Speciation Analysis
- Mercury Speciation Analysis
- Vanadium Speciation Analysis
- Lead Speciation Analysis
- Thallium Speciation Analysis
- Manganese Speciation Analysis
- Metal-Cyanide Speciation Analysis
- Iron Speciation Analysis

Selective Sequential Extractions (SSE)

Price on request

When investigating mercury contaminated soils at legacy mining and industrial sites, measurements of the concentrations of total mercury in the soil are clearly necessary. However, the best approach to site remediation sometimes requires a fuller understanding of the environmental bioavailability and mobility of the particular mercury compounds found at the site.

 

There is growing interest in the regulatory community concerning bioavailability and Brooks Applied Labs (BAL) remains one of the foremost experts in providing commercially practical solutions to determine the concentrations of various mercury compounds or fractions. Through advanced separation techniques, we are able to quantify mercury concentrations in sediments according to specific compound or fraction of interest.

 

One of the methods used at BAL to assess the concentrations of mercury compounds in soils that belong to these specific classes is a selective sequential extraction (SSE) procedure. These selective sequential extractions represent the mobility of specific classes of mercury compounds and can be classified as fractions that are water soluble, weak acid soluble, organo-complexed, strongly complexed, or mineral bound. The first three of these fractions have been shown to be significantly more mobile, bioavailable, and susceptible to methylation.

 

Data regarding of the concentrations and ratios of these mercury compounds in contaminated soils can be critical to successful site remediation and containment of potentially hazardous materials.

 

It has become increasingly common for risk assessment and treatability studies to require speciation analyses to determine the potential mobility of toxic contaminants at varying sites. Looking at extractable speciation results can be helpful for these studies; however, this approach can only provide a snapshot of how much of each contaminant molecule is readily leachable at any given time.  In reality, the conditions in soil and sediment samples can change over time depending on many factors, including the amount of rainfall, contaminant plume movement, and the hydrogeology at each individual site. Contaminants trapped in various mineral phases can be mobilized under varying site conditions, and even the treatment technologies used to remediate a site can affect the chemistry of the targeted environment and the subsequent lability of certain metals.

 

At BAL, we have proprietary procedures for the SSE of certain metals in soils, sediments, and similar solid matrices using a series of solutions with an increasing ability to solubilize and extract the solid-phases. Rather than identify specific metalloid species, the metals are fractionated in accordance with their interaction with the substrate components. For specific metals we also have more focused SSE procedures that have the capacity to elucidate molecular forms or groups of molecular forms of the each specific metal.
