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
