SMS 100 Mercury analysis directly on solid samples from the undisputed leader in Atomic Spectroscopy

The SMS 100 is a dedicated mercury analyzer for the determination of total mercury in solid and liquid samples using the principle of thermal decomposition, amalgamation and atomic absorption described in U.S. EPA Method 7473. The sample is heated in an oxygen rich furnace, to release all the decomposition products, including mercury. These products are then carried in a stream of oxygen to a catalytic section of the furnace. Any halogens or oxides of nitrogen and sulfur in the sample are trapped on the catalyst. The remaining vapor is then carried to an amalgamation cell that selectively traps...

Benefits No Sample Preparation The SMS 100 eliminates the need for dissolution techniques, complicated chemistry and hazardous wastes involved with traditional mercury analysis. A solid sample can be analyzed in approximately 5 minutes. Extremely Low Detection Limits By using a 25 cm optical path length cell, the SMS 100 is capable of extremely high sensitivity and low background levels, achieving a detection limit of 0.005 nanograms of mercury. Full Automation for Maximum Productivity The SMS 100 automatically transfers sample weights from your lab balance. Additionally, its 70-position autosampler...
