Mercury is a persistent, global, and toxic element. It does not degrade, but it changes forms as it cycles through the environment. When mercury is emitted, it can be transported over long distances and re-deposited.Read More
Teledyne Leeman Labs Blog
Teledyne Leeman Labs has been in the mercury (Hg) analysis business for more than 30 years. We have had a variety of product lines reach new markets and address tighter regulations. In that time, one thing has remained constant across all our instruments: the need for accurate mercury standards to form the building blocks of the calibration curve. Analytical results are only as reliable as the calibration curve to which they are compared, and creating stable mercury standards comes with unique challenges.Read More
Teledyne Leeman Labs offers multiple mercury (Hg) analyzers which can determine total mercury concentrations in samples at the ultra-trace level. The final installment of this three-part blog series will be an introduction to the QuickTrace line of mercury analyzers: the QuickTrace M-7600 and the QuickTrace M-8000.Read More
In Part 1 of this series, sample collection, container types, and preservation techniques for low-level total mercury (Hg) analysis were discussed. In Part 2, I will highlight contamination sources from chemicals and the potential for analyte loss associated with digestion protocols.Read More
Mercury (Hg) determination at the ultra-trace level is an essential part of environmental assessment and drinking water monitoring. But this type of analysis comes with distinct challenges.Read More
The gold standard. Go for the gold. A gold medal.
Gold is highly prized for its beauty, as a measure of wealth, a jewelry mainstay and more. When it comes to the analysis of mercury, gold has a very particular value in obtaining data at the ultra-trace level.Read More
Trace elemental analysis
Teledyne Leeman Labs has specialized in trace elemental analysis for over 40 years. With initial success in Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP-AES), also referred to as Inductively Coupled Plasma-Optical Emission Spectroscopy (ICP-OES), Teledyne Leeman Labs went on to develop innovative product lines. Those included branching out into various elemental analysis techniques, including DC Arc and Mercury Analysis. Our elemental analysis instruments can be found in laboratories across the world, providing service to a range of industries. From agriculture to aerospace and food to forensics, Teledyne Leeman Labs is dedicated to providing world-class instruments for trace elemental analysis.

Atomic absorption spectroscopy
Atomic absorption spectroscopy (AAS) is one of the first commercially available elemental analysis techniques. This tried-and-true method remains a top choice for its simplicity and reliability.Read More
The proliferation of mercury in fish is a well-documented environmental problem. Mercury accumulates in fish tissue from natural and anthropogenic source in bodies of water where the fish live. The microorganisms at the base of the aquatic food change convert the elemental mercury into organic methylmercury, which binds tightly to the proteins in fish tissue.Read More

An abandoned ammo factory in Kings Mill, Ohio is on the EPA list as one of the most contaminated sites in the country. The site, once home to the Peter’s Cartridge Company, could be the new home to luxury apartments and commercial office space overseeing the Little Miami River. The $25 million plan, which includes 120-130 apartments and 23,000 square feet of commercial space, is dependent on whether the site can be remediated from the mercury, copper and lead that has contaminated the soil for more than a century.

Soil and dust in homes often become the primary resting places for environmental toxins such as metals and metalloids that come from vehicle traffic and a variety of industrial sources. Residents within urban settings have a higher rate of exposure to contaminated dust from inhalation, ingestion and dermal contact. As a result, dust ingestion is often regarded as the primary source of low-dose mercury in urban children who spend much of their time indoors.
