RA-915M / RP-92

Principle of operation

Is based on the absorption of the 254-nm resonance radiation by mercury atoms using Zeeman correction for background absorption.

Features and 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.

Areas of application

RA-915M mercury analyzer with RP-92 attachment can be used in ecology, sanitary, medicine, and geological-geochemical survey.

Control of mercury content in:

• waste, natural, and dinking waters;
• foodstuffs;
• biological objects (urine, hair, blood, etc.) for diagnosis of risk groups.

Occupational pathology and toxicology surveys:

• screening population survey;
• instrumental monitoring of medical treatment of mercury intoxication and further rehabilitation.

Mercury pollution monitoring:

• monitoring of a demercurization process involving any chemical reagents;
• quality assurance of the demercurization;
• determination of mercury content in washouts;
• determination of mercury content in surface and ground waters.
