RA MERCURY ANALYSERS
RA series mercury analysers use the reducing-vaporization method of analysis to measure Hg concentration in liquid samples.
RA-5 FULLY SCALABLE, TOUCH SCREEN ANALYSER
- Stand-alone system with touch screen, no PC connection required
- Reduction of the demand for tin (II) chloride by approx. 80% compared to flow injection systems and therefore 80% less waste
- Extremely high particle handling, samples do not have to be filtered after digestion
- Internal gas supply
- Optional auto-sampler can be retrofitted for larger sample volumes
- Meets ASTM D 3223-02, EN-1483, EN-12846 and DIN-ISO 16772 standards
- The minimum sample volume required for measurement is 5mL
- Automatic identification of mercury and non-mercury peaks
RA-4300 NIPPON MERCURY ANALYSER FOR LIQUIDS WITH ADDED SAMPLE PREPARATION
- Using the method of reduction vaporisation with tin chloride, a variety of liquid samples can be analysed
- High matrix tolerance due to Direct-Discrete-Purge technology
- Low reagent consumption
- Automatic Quenching function
- Settable purging times to flush “free chlorine” to avoid interferences
- AA detector only, LOD’s down to 5ppt
- Non-continuous flow design reduces running cost dramatically
- No carrier gas required
- Integrated auto-sampler means small footprint
RA-4500 MERCURY ANALYSER FOR LIQUIDS
- Fully automated sample digestion and analysis system
- Samples are digested automatically according to the EN 1483
- Effective acid digestion is achieved with precise thermal control, non-contact LED sensors and fully automated software
- Small sample volume required (5ml) reduces reagent consumption
- Ideal for drinking, industrial, sea, waste, river and lake waters
THE RA-4300FG+ – THE TOTAL SOLUTION FOR TRACE MERCURY ANALYSIS
- Has an optional HEPA filtration system to maintain a clean environment
- Comes with a built-in purging system to keep your reagents clean during analysis
- Also has one of the most advanced and sensitive atomic florescence spectroscopy (AFS) detectors available
- Can easily achieve ppt and sub-ppt detection levels for Mercury and can achieve these detection limits in liquid sample types including drinking waters, natural waters, wastewaters and digested solids
- Offers user-friendly, intuitive software which allows the user to select for operation by EPA 1631E, EPA 245.7 or normal measurement
- Includes all the standard QC requirements for EPA measurements, allowing automated control of the analyser according to pass/fail QC requirements
