A modified EPA 3015A digestion alternate test procedure (ATP) approved by EPA Region 10 will be discussed. Data showing a microwave method detection limit (MDL) sample preparation at 1 ppt as well as samples in the 1–10 ppt range will be highlighted. Specific points covered will include: How the ICP-MS method can meet if not beat requirements in EPA Method 1631, Revision E The reproducibility of mercury curves starting at 0.500 ppt How mercury curves starting at 50 ppq can be achieved with ICP-MS The quirks seen with mercury at the parts-per-trillion level and how to resolve them. Key Learning Objectives: How microwave digestion can be performed easily and reproducibly in the 1–10 ppt concentration range for mercury How to perform an ATP mercury microwave sample preparation procedure approved by EPA Region 10 How to tune an ICP-MS system to analyze mercury at a 0.5000-ppt concentration Quirks of mercury analysis at the parts-per-trillion level and how to address them Who Should Attend: Environmental chemists wishing to improve the detection of mercury at ultratrace levels Scientists at contract and environmental laboratories seeking better sample preparation methods Analytical chemists interested in applying ICP-MS methods to meet EPA requirements For questions, please contact Kristen Moore at kmoore@advanstar.com.
