RA-915 F Field Mercury Analyser with Direct Thermal Decomposition

Achieve accurate, reliable and cost-effective mercury measurements with the RA-915 F Field Mercury Analyser—designed for direct thermal decomposition across the broadest range of sample matrices. This compact three-unit system analyzes complex samples ‘as is’ without pre-treatment, combining atomic absorption spectrometry with programmable thermal release for interference-free results. Ideal for environmental field surveys, mine site monitoring, petroleum testing and rapid contamination assessment. The real-time feedback system handles soils, water, crude oil, coal and biological tissues with ppb-level sensitivity in 1–5 minute cycles. No wet chemistry, compressed gases or gold traps needed—air carrier operation reduces complexity and field deployment costs. The modular design fits mobile laboratories and remote testing stations. Fast warm-up and zero memory effect enable high-throughput screening. Universal power and lightweight construction support generator or battery operation in any location. Share your field testing requirements—our team will configure the RA-915 F with sample boats and methods for your on-site mercury analysis program.
