Mercury Analyzer RA-915M

Mercury Analyzer RA-915M

Mercury Analyzer is a portable multifunctional atomic absorption spectrometer with Zeeman background correction, which eliminates the effect of interfering impurities. It is the only high sensitivity and selectivity instrument that does not require gold amalgam pre-concentration and subsequent regeneration steps. This enables the user to conduct real time air monitoring and detection of a mercury vapor. Being combined with pyrolysis or cold vapour attachments for liquid and solid sample testing, the instrument can determine mercury content in water, soil, food products, natural and stack gases, may be used for dental and toxicological applications, etc.

The mercury analyzer RA-915M is a unique all-purpose high sensitivity analytical instrument for measuring mercury, especially for the real time detection of mercury vapor in air, mercury detection in water, natural and stack gases, oil and condensate, solid and sediments, foodstuff and so on.

RA-915M Mercury Analyzer is a portable multifunctional atomic absorption spectrometer with Zeeman background correction, which eliminates the effect of interfering impurities. It is the only high sensitivity and selectivity instrument that does not require gold amalgam pre-concentration and subsequent regeneration steps. This enables the user to conduct real time monitoring and detection of a mercury vapor. Being combined with an RP-92 Cold Vapor accessory for water and PYRO-915+ pyrolysis attachment for solid sample testing, the instrument is designed to determine mercury content in ambient air, water, soil, natural and stack gases, dental and medical testing and diagnostics, analysis of food and marine life, etc., the mercury detection limits being as low as 0.5 ng/m3 in air and 0.5 ng/l in water.

areas of application

The RA-915M portable mercury analyzer system enables coping with any complex problems involving mercury detection in natural media and in technological process monitoring.

Demercurization monitoring:

  • search and localization of indoor and outdoor mercury contamination in continuous air analysis mode, including those performed from moving vehicles;
  • monitoring of a demercurization process involving any chemical reagents;
  • quality assurance of the demercurization;
  • mercury assaying in construction materials and surface wash-outs.

Handling the toxicology and occupational safety problems:

  • proximate analysis of biological objects (urine, blood, hair, and exhaled air) finding out risk groups;
  • screening examination of population;
  • finding out risk groups;
  • instrumental monitoring of a mercury intoxication treatment and of the following rehabilitation.

Rapid-analysis of complex objects:

  • combustible deposits (hydrocarbon gases, natural gas condensate, oil, coal, peat, and shale oil;
  • raw materials and industrial products;
  • ecological and geochemical samples, biological objects, foodstuffs, cosmetics, and medical preparations.

Geological and geochemical survey:

  • study of mercury cycles of natural and technological origin;
  • prospecting of mineral deposits;
  • Mercury assaying in natural gases, water, rocks and ores.

Ecological survey:

  • continuous background mercury vapor monitoring in the atmosphere;
  • various ecological surveys of mercury haloes of technological origin and detection of emission sources.
