Areas of Applications
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.
