Spectroscopy ICP On-Demand Webinar Series
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.

Getting accurate IR spectra on monolayer of molecules
April 18th 2024Creating uniform and repeatable monolayers is incredibly important for both scientific pursuits as well as the manufacturing of products in semiconductor, biotechnology, and. other industries. However, measuring monolayers and functionalized surfaces directly is. difficult, and many rely on a variety of characterization techniques that when used together can provide some degree of confidence. By combining non-contact atomic force microscopy (AFM) and IR spectroscopy, IR PiFM provides sensitive and accurate analysis of sub-monolayer of molecules without the concern of tip-sample cross contamination. Dr. Sung Park, Molecular Vista, joined Spectroscopy to provide insights on how IR PiFM can acquire IR signature of monolayer films due to its unique implementation.
