RA-915 Lab Direct Mercury Analyser with Zeeman Correction

Achieve ultra-trace mercury detection with the RA-915 Lab Mercury Analyser, engineered for direct thermal decomposition analysis across diverse sample matrices. This advanced atomic absorption system combines Zeeman background correction with fast thermal release—delivering ppb-level sensitivity without chemical pretreatment for most samples. Ideal for environmental labs, petroleum testing, food safety and industrial hygiene applications. The automated 45-position sampler handles solids, liquids, oils and biological tissues with minimal sample prep. Results in 1–5 minutes per sample mean high throughput for routine screening and compliance monitoring. Built-in method library, calibration storage and network export simplify data handling. Tell us your sample types and detection requirements—our team will configure the RA-915 Lab with the optimal accessories and methods for your mercury testing program.
