Save time and go direct for mercury analysis

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.
