PORTABLE ZEEMAN MERCURY VAPOR ANALYZER

Types of analysis  


Mercury analyzer RA-915 light is a low cost analytical instrument for measuring mercury concentrations in air. It is intended for assesment of indoor/outdoor air quality in residential and industrial settings.

Mercury Analyzer RA-915 Light 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. 

METHOD

Atomic absorption spectrometry

PRINCIPLE OF OPERATION

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