RA915M Mercury Analyzer with NEW Pyrolyzer PYRO-915+ 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 prodcuts, natural and stack gases, may be used for dental and toxicological applications, etc. RA-915M Mercury Analyzer with new pyrolyzer PYRO-915+ (with large optical length of analytical cell and heated windows of the analytical cell is developed for unique direct mercury determination (no pretreatment procedures required) in complex organic samples at the level of ppb and even sub ppt levels (depending on environmental conditions and attachments used)

The Advantages

  • Fast mercury determination without its preliminary accumulation on a gold trap, results in under 1 minute (depends on sample nature);
  • Broad dynamic measurement range: 5 orders of magnitude;
  • Variable temperature of the decomposition chamber allows selection of optimal atomization. Preset modes for various types of samples are embedded in the software;
  • Heated analytical cell rules out interferences even for a sample with a high content of organic substances and chlorides;
  • Boost heated function (stepwise heating of the atomizer) allows to control the completeness of the mercury release from the sample;
  • Monitoring the background absorption during measurement allows effective selection of the permissible weight of samples of any composition, thereby avoiding analysis errors;
  • Visualization of mercury output from the sample, user-friendly computer interface;
  • Calibration coefficient is set using standard mercury-containing sample of any composition, high calibration stability;
  • Automatic control of the air flow rate, no carrier gas is needed.


  • No pretreatment procedures required: Unique direct mercury determination in liquid and solid samples (including complex matrix organic samples): waste water, blood, foodstuffs, oil and oil products, bottom sediments, rocks etc.;
