Skip Kingston discusses speciation, including Cr and Hg, as well as other species less studied and published on such as Se and As.
He looks at the role they play in toxicology, nutrition and health care. These analyses are not simple and require new tools in chemistry and mass spectrometry.
He will also discuss the new mathematical dimension that has been added to the analysis and quality assurance of these more difficult and sophisticated analysis that are now needed by FDA, CDC, and others.
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.
