Demystifying Interference Removal
Accurate and precise analysis is key to ensuring data quality and confidence in results. Interferences that normally arise can affect both accuracy and precision. During this web seminar, we will discuss interferences in ICP-OES and ICP-MS, focusing on potential sources of interference and their identification and removal by hardware or software techniques

Analysis of Mercury at Parts-Per-Trillion Levels by ICP-MS Using Microwave Sample Preparation
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.

ICP-MS for Arsenic Speciation
ICP-MS, interfaced with either an ion chromatography (IC) or liquid chromatography (LC) system, has become the gold standard for the speciation of arsenic in environmental matrices because of its high selectivity and highly sensitive detection. Given that inorganic arsenic in rice has become an important issue globally, more and more laboratories are adopting hyphenated ICP-MS approaches.
