RA-4300A Mercury Analyzer

RA 4300A

Cold Vapor Atomic Absorption (CVAAS)

The NIC RA-4300A Mercury Analyzer is one of the latest innovations from Nippon Instruments Corporation (NIC). The RA-4300A performs cold vapor atomic absorption for mercury analysis according to traditional EPA and other regulatory methods in waters, wastewaters, soils, sediments, sludges & more. The RA-4300A is unique in that it performs these methods using automated direct purge technology as opposed to continuous flow, which allows for a waste reduction of over 80%.  It does this without the need for any compressed gases and includes a built-in enclosure to protect the integrity of your samples.

RA-4300A Mercury Analyzer Key Features:

  • Discrete, direct purge of mercury from each sample…simplifying operation while eliminating carryover and reducing waste
  • No compressed gases required thanks to a built-in carrier gas pump, which reduces operational costs
  • Detection down to low ppt without the use of gold amalgamation or CVAFS
  • Automatic quenching of potassium permanganate (or other oxidants)…removing this step from the user’s requirements reduces time/cost by improving efficiency in the lab
  • Ability to use multiple sample tubes
  • Sample: waters, wastewaters, liquid & solid digestates, & more
  • Detection method: Cold-vapor atomic absorption spectrometry
  • Measuring range: 0.0005 to 100 ppb
  • Number of samples: 80 per tray on autosampler
  • Measuring method: Reducing vaporization
