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.
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.
- 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
