Editors’ Series: Analysis of Mercury at Parts-Per-Trillion Levels by ICP-MS Using Microwave Sample Preparation

This webcast was recorded on May 29, 2014.

This seminar will discuss the preparation of liquid samples for mercury analysis using microwave digestion. 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.
