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

RA-5 mercury analyser image

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

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

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

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
