FEATURES
AND BENEFITS |
|
- direct detection of mercury without its preliminary
accumulation on a gold sorbent
- real-time operation mode wide dynamic measuring range
(more than three orders of magnitude 0.1-100 μg/m3)
- field operation from a built-in battery for performance
of ambient air
- English-language software

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.
Laboratories involved in environmental monitoring and safeguarding
public health care need means for rapid and reliable analysis
of mercury contamination in the environment.
Atomic absorption spectrometry
Is based on the resonance absorption of the 254-nm radiation
by mercury atoms using Zeeman correction for nonselective absorption
