Reference : RA-915M 

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 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.

Features & Benefits

• Simple to operate, fully automated, self validating analyzer
• Rugged/Versatile design for laboratory and field mobile conditions
• Ultra low detection limit and highest selectivity
• Real-time operation mode for air and gases
• Direct determination of mercury in liquid and solid matrices within 60 seconds (attachment required). No sample preparation, no use of hazardous chemicals or bottled gases 
• Built-in performance verification test cell and auto zero function
• Wide dynamic measuring range (four orders of magnitude)
• Controlled by a keypad or a computer via USB interface
• Data logger for 122 hrs of data acquisition, averaging, and storage
• Rechargeable battery for up to 12 hours operation

RA-915M Mercury Analyzer with 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 few µg/kg.

Using of RA-915M spectrometer with background correction and a developed two-chamber catalyst atomizer PYRO-915+ allows direct analysis of complex-matrix samples.

PYRO-915+ atomizer consists of two chambers. The first is for evaporation of liquid and pyrolysis of solid samples. The second chamber is continuously heated about 800°C. There, all mercury compounds are dissociated and smoke and interference compounds are burst.

The power supply unit of the attachment provides stable air flow speed and temperature of chambers and analytical cell.

Feature & Benefits

• Unique direct mercury determination (no pretreatment procedures required) in liquid and solid samples (including complex matrix organic samples): waste water, blood, foodstuffs, oil and oil products, bottom sediments, rocks etc.;
• Fast mercury determination without its preliminary accumulation on a gold trap;
• 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.
