Mercury is among most abundant environmental pollutants which adversely affects ecological systems and human beings. It shows high toxicity, mobility, and ability of accumulation in trophic chains of water and continental biocenosis. Therefore, it is recognized to be one of the most hazardous global environmental pollutants.
Mercury penetrates into human organisms through breathing and with foodstuffs contaminated by methylated mercury (primarily, with fish and other seafoods).
Laboratories involved in environmental monitoring and safeguarding public health care need means for rapid and reliable analysis of mercury contamination in the environment and human beings.
Multifunctional portable mercury analyzer RA-915+ features a unique capability of performing direct, fast, and precise measurements of mercury vapor and mercury concentration in various media.
| MEASUREMENT PRINCIPLE |
RA-915+ is an atomic absorption spectrometer, which employs the effect of the resonance radiation absorption by the mercury atoms.
- Proprietary scheme of the Zeeman correction for non-selective absorption provides high measurement accuracy irrespective of interfering factors, such as dust, aerosols, absorbing gases and vapors.
- Multipath cell with an effective optical length of 10 m provides the highest measurement sensitivity.
| RA-915+ ADVANTAGES |
- Versatile analyzer for air, liquids and solids analysis in lab and field conditions
- Ultra low detection limit and the highest selectivity
- Real-time operation mode for air and gases
- Direct detection of mercury without pre-concentration steps in complex-matrix samples
- Wide dynamic measuring range
- Control by a keypad or by a computer
- State-of-the art software
- Data logger
| Application samples |

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