Spectradyn Technologies LLC - Zeeman mercury analyzer RA-915+

• ULTRA LOW DETECTION LIMIT
• DIRECT MESUREMENTS WITHOUT PRELIMINARY MERCURY CONCENTRATION ON SORBENTS
• HIGH SELECTIVITY OF ANALYSIS
• WIDE RANGE OF APPLICATIONS

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 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.

Principle of operation - "Cold Vapor" Technique
Analysis is carried out using an RP-91C attachment. Mercury, which is present in various chemical compounds, is sublimated and atomized in a two-stage pyrolysis reactor.
