As more emphasis is placed on the monitoring and determination of mercury emissions, both private and public institutions are looking at characterizing soil, sediments and waste water samples.
The challenges in mercury analysis are well known to analysts who had often faced a number of issues due to either the tedious sample preparation process or the Hg analysis step. The latter, even with the latest generation of ICP-MS or cold vapour systems, may create a memory effect even after long cleaning cycles.
Direct mercury analysis, as described in EPA Method 7473, is an alternative to these methods and has been used successfully to determine total mercury in solid, liquid and gas samples.

The Milestone DMA-80 has been at the forefront of direct total mercury analysis for almost two decades. The challenges in mercury determination are well known to analysts who who often face a number of issues connected with tedious sample preparation process or the mercury analysis steps causing memory effect even after long cleaning cycles performed using latest generation of ICP-MS or cold vapor systems.
The DMA-80 mercury determination system can analyze any matrix (solid, liquid or gas) without any pre-treatment or chemical additions in as few as 6 minutes in full compliance with EPA method 7473. With thousands of units installed, Milestone defines the benchmark for direct mercury determination a wide range of industries: environmental, food energy, cement, cosmetics, agriculture, mining and petrochemical.
Milestone DMA-1 is a direct mercury analyzer of solid, liquid, and gas samples. Analysis time is 5 minutes only and no sample preparation is required. The DMA-1 analyzer is based on the principles of sample thermal decomposition, mercury amalgamation and atomic absorption detection. The DMA-1 shares the same technology of the Milestone DMA-80 series, the most successful direct mercury analyzer in the market with thousands of units installed in 80 different countries worldwide.
