Ohio Lumex - Model RP 92 -Mercury in Liquid Analyzer

SHARE
Used as an attachment for the RA-915M, the RP-92 provides a unique method for determining mercury concentrations in liquid samples such as water, blood and urine for environmental monitoring, technological process controls, medicine and other scientific research. The RP-92 attachment is a generator of mercury vapor which is produced by reducing Hg (II) into its elemental form using the cold vapor technique (CV).

scientific research
  • Based on differential Zeeman Atomic Absorption spectrometry using high frequency modulation of light polarization.
  • Mercury determination without gold amalgamation
  • Ability to use single-path or multi-path analytical cell allows for a wide dynamic range of up to 3 magnitudes
  • Wide dynamic measurement range of up to 3 magnitudes without sample dilution
  • Visualization of mercury output from the sample, user-friendly computer interface;
  • Calibration stability using NIST Traceable Standards
  • Zeeman Background Correction rules out any potential interferences even for a sample with a high content of organic substances
  • Portability
  • Measurement of low mercury concentration in drinking water and natural water
  • Control of mercury content in wastewater and washouts;
