RA-915M Multifunctional Zeeman mercury analyzer RA-915M is a supersensitive and highly selective portable analyzer that allows real-time mercury measurement in ambient and indoor air. Being combined with dedicated attachments, the analyzer is used for mercury determination in a wide range of objects, such as solid and liquid samples, biological materials, and various gases. RA-915M-based sets can be used in stationary and field laboratories. Differential Zeeman atomic absorption spectrometry with high frequency modulation of light polarization (ZAAS-HFM). • Direct continuous measurement; no gold traps, no compressed gases • Ultra-low detection limit and highest selectivity • Real-time operation mode for air and gases with 1 s response time • Attachments for direct mercury determination in liquids, solids, and hydrocarbon gases • Wide dynamic measuring range (six orders of magnitude) • Auto zero drift correction • Self-diagnostic with a built-in test cell • Controlled by a keypad or a PC via USB interface • Data logger for 122 hours of data acquisition, averaging, and storage • Rechargeable battery for up to 8 hours operation APPLICATIONS RA-915M is used for background air monitoring, mercury surveys including continuous measurements from vehicles, indoor and outdoor pollution detection and mapping, demercurization control, occupational health and safety, geochemical exploration, etc. Direct measurements comply with EN 15852 standard for the determination of total gaseous mercury in the air.
