Nippon RA-4500 Fully Automated Reducing-Vaporization Mercury Analyser


Mercury analysis by CVAAS to include fully automated sample digestion and analysis


The RA-4500 is the highest grade model of our reducing-vaporization mercury analyser, which was developed to meet customer’s needs for “more efficient measuring methods in compliance with various testing methods without troublesome wet pre-treatment.”

For the first time ever, measuring steps from pre-treatment through to measurement of liquid samples, such as tap water, industrial waste water and soil eluate, are fully automated. The required amount of sample is as small as 5 mL, and reagents as well as waste fluid can be significantly reduced. Thus, compared to previous methods, operation cost can be reduced by up to 50%.
