  • Increase Mercury Vapor Detection Range by 10X

    Vapor dilution module extends detection range of J505 from nanograms to milligrams How it works: The new 10:1 dilution module for the J505 reduces the concentration of mercury vapor in the sample stream by a factor of ten, allowing for a much higher detection limit. Rather than the standard upper detection limit of 500 µg/m3, ...

  • Mercury Analysis

    Characteristics of Mercury What is Mercury? Mercury is a naturally occurring silver-colored metallic element noted for its occurrence as a liquid at room temperature and toxic to living organisms. This silvery, opaque liquid metal is very dense, yet has a high surface tension that causes it to form tiny perfect spheres in the pores of the rocks it is found in. It is ...

  • Mercury Spill Control Procedures

    Mercury is a dangerous neurotoxin that can have damaging affects on both the central nervous system and renal system of humans. Exposure to mercury can cause serious developmental delays in children, and high level exposure is life threatening. When exposed to air, mercury vaporizes, readily becoming a dangerous aerosol that can be absorbed into the lungs and spread throughout the body. This is ...


  • Mercury stabilization takes the sting out of mercury

    In elementary form, mercury is a danger to humans and the environment. But chemically bound to sulfur it loses its toxicity and can be disposed safely. The process which transforms the highly toxic metal into an unproblematic red powder is called mercury stabilization. As a specialist for cleaning mercury contaminated soil and waste by vacuum distillation econ also offers a process for mercury ...

    C1.1 | Halogens and Sulfur in Coals and their Influence on Co-benefit Mercury Capture Bernhard Vosteen | President, Vosteen Consulting Gmbh Not only the range of the coal mercury content itself, but also the range of the native halogen and sulfur contents in coal are of great influence on co-benefit mercury capture, wet and dry. The ...

  • Determination of Ultra-Trace Mercury Vapor Levels from Industrial & Military Metal Components

    For many years, scrap metal reclaimers did not separate the materials containing mercury from other metals. Such things as mercury switches, dental amalgam, thermometers, and refining wastes from copper, gold and silver were processed along with the typical industrial metals. The result is that a significant portion of the Ferrous and non-Ferrous metals and alloys used today contain some metallic ...

  • New University of Minnesota study documents mercury vapor emission levels and need for safer packaging, storage and transportation of fluorescent lamps

    Results of a recent study conducted by the University of Minnesota School of Public Health, Division of Environmental Health Sciences suggest that most containers used for storage and transportation of used fluorescent lamps to recycling centers do not provide necessary levels of protection against mercury vapors emitted from broken lamps. The new study, published in the March issue of the ...

  • Mercury Spill Control Procedures

    Mercury is a known neurotoxin that is extremely toxic even in small amounts. It directly affects the central nervous and renal systems, causing developmental delays, motor and brain problems like those associated with autism. Mercury"s hidden danger also lies in when at room temperature, when exposed it vaporizes readily. Once ...


  • Aqueous and vapor phase mercury sorption by inorganic oxide materials functionalized with thiols and poly-thiols

    The objective of the study is the development of sorbents where the sorption sites are highly accessible for the capture of mercury from aqueous and vapor streams. Only a small fraction of the equilibrium capacity is utilized for a sorbent in applications involving short residence times (e.g., vapor phase capture of mercury from coal-fired power plant flue gases). So, dynamic capacity rather than ...

  • The source and risks of mercury in the offshore industry

    Oil in Gas and RocksAlmost all oil and gas is found within the tiny spaces in sedimentary rocks, mainly sandstone and coarse-grained limestone. Bedrock limestone and sandstone, even though hard, also contain lots of pores that can contain water or oil or gas and other elements. Along with the gas and oil is a mixture of sand, silt & mud. This sludgy silt mud is rich in heavier metal elements ...

  • Determination of mercury speciation in fish tissue with a direct mercury analyzer

    Knowledge of mercury speciation in tissue is valuable for assessing potential toxicological effects in fish. Direct mercury analyzers, which use thermal decomposition and atomic absorption spectrometry, have recently gained popularity for determining organic mercury after procedural solvent extraction from some environmental media, although quantitative recovery from lipid‐rich materials, such ...

  • L.A. mercury spill provides opportunity for education

    The uncertainty surrounding a mercury spill on a Los Angeles subway platform this past December was reported by many leading news organizations, including coverage by the Los Angeles Times, CNN and Fox News, among others. Many of these news stories focused on the slow response to the incident and the potential for this to have been associated with terrorism. While these are valid concerns that ...

  • Overview of mercury control in coal-fired power plants

    During combustion, the mercury (Hg) in coal is volatilized and converted to elemental mercury (Hg0) vapor in the high temperature regions of coal-fired boilers. As the flue gas is cooled, a series of complex reactions begin to convert Hg0 to ionic mercury (Hg2+) compounds and/or Hg compounds (Hgp) that are in a solid-phase at flue gas cleaning temperatures or Hg that is adsorbed onto the surface ...

  • Determination of mercury with on-line addition of stannous chloride uUsing an axial ICP-OES

    Mercury is one of the most toxic heavy metals in the environment. It is therefore important to routinely monitor the Hg level in many types of samples. The US EPA approved methodology for the determination of Hg uses the cold vapor technique with stannous chloride as the reducing agent1. This methodology is applicable to Hg determinations in a range of waters (drinking, ground, surface, sea and ...


  • Using FIMS to determine mercury content in sewage sludge, sediment and soil samples

    Tim Flow Injection Mercury System (FIMS) is a dedicated system that integrates flow injection mercury cold vapor generation with a very sensitive detector. The exceptional system stability and the long path measurement cell provide instrumental detection limits as low as 5 ng/L using a sample volume of 5(H) jxL. The improved sensitivity of the FIMS permits sample dilution, therefore reducing the ...
