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.

RA-915M mercury analyzer with RP-92 attachment is used for determination of mercury concentration in liquid samples (water, blood, urine).

RP-92 attachment is intended to transfer bound Hg from ion to atomic form using “cold vapor” technique.

Feature & Benefits

• Any sample preparation technique can be used
• Ability to use single-path or multi-path analytical cell depending on the task (background measurement or analysis of highly contaminated waste water)
• Mercury determination without gold amalgam pre-concentration
• Wide dynamic measurement range more than 3 exponent (without sample dilution)
• Detection limit is on background level of mercury content in natural waters
• Visualization of the process of Hg coming from the sample, user-friendly interface
• Calibration stability (it’s necessary to check the stability once a day)
• Possibility to carry out field analysis without a PC
• Measurement of low Hg concentration in drinking and natural water, foodstuffs
• Control of Hg content in wastewater and washouts
• Mercury determination in blood, urine and other liquid samples
