Mercury Analyzer

1. Overview

• The mercury analyzer RA-915M is a unique all-purpose high sensitivity analytical instrument for measuring mercury, especially for the real-time detection of mercury vapor in air, mercury detection in water, natural and stack gases, oil and condensate, solid and sediments, foodstuff and so on.
• RA-915M Mercury Analyzer is a portable multifunctional atomic absorption spectrometer with Zeeman background correction, which eliminates the effect of interfering impurities. It is the only high sensitivity and selectivity instrument that does not require gold amalgam pre-concentration and subsequent regeneration steps. This enables the user to conduct real time monitoring and detection of mercury vapor. Being combined with an RP-92 Cold Vapor accessory for water and PYRO-915+ pyrolysis attachment for solid sample testing, the instrument is designed to determine mercury content in ambient air, water, soil, natural and stack gases, dental and medical testing and diagnostics, analysis of food and marine life, etc., the mercury detection limits being as low as 0.5 ng/m3 in air and 0.5 ng/l in water.

2. Features and benefits
