Arsenic

Mar 8, 2019

Arsenic As
Arsenic is naturally-occurring throughout the environment and also widely used as a preservative for treated wood and as a pesticide in fields where we grow our food. Because of its chemical nature, it is frequently bioavailable and easily absorbed. Accurate and precise measurements of this classified human carcinogen are critical for managing our environment and protecting human health and safety. At Brooks Applied Labs, we have both the innovation and the expertise to provide you with ultra-low arsenic and arsenic speciation for virtually any matrix type. Please contact us to find out which arsenic test is the appropriate method choice for your samples.

Mercury

Mercury Hg
Mercury is not very abundant in the planet’s crust; however, even modest increases in the quantity of mercury being introduced into the global environment is a matter of considerable and growing concern. Mercury contamination can threaten the health of humans and wildlife, from industrial sites to the most remote wilderness areas. Mercury is considered a global pollutant since it can affect the environment in areas far removed from the point of its original release.

Since 1982, Brooks Applied Labs has devoted significant resources to the research and development of the analytical methods and instrumentation necessary to quantify mercury and methylmercury concentrations at ultra-low levels in even the most complex matrices. Our early research contributed substantially to the development and validation of EPA Method 1631 and EPA Method 1630 for the determination of mercury and methylmercury in waters at sub-parts-per-trillion levels.

Over the decades we have developed and perfected our analytical methods to determine mercury and methylmercury concentrations in even the most complex matrices.

We routinely analyze the following for mercury and methylmercury with some of the lowest detection limits available to our clients:

Monitoring for Dimethylmercury

Jun 16, 2016

Dimethylmercury (DMeHg) is an extremely dangerous neurotoxin that can bioaccumulate in the body following exposure. This compound is not used in industry due to the risks involved, but it has been found to be produced under certain conditions when wastes containing mercury are stored. DMeHg is a liquid, but it has a very low vapor pressure, so it can be readily detected in the air as well. Recently, there has been a growing concern regarding exposure to DMeHg for workers.

Brooks Applied Labs developed a method for the detection of DMeHg and other volatile mercury compounds decades ago. Our primary method utilizes cold vapor generation with gas chromatography coupled to an atomic fluorescence spectrophotometer (CV-GC-AFS), and this method is validated by a secondary technology using reverse-phase chromatography for the separation and ICP-MS detection (RP-ICP-MS). An added benefit of these methods is the capability to quantify methylethylmercury (MeEtHg) and diethylmercury (DEtHg) compounds, allowing for a more complete evaluation of the mass balance of the mercury species in a sample.
