The productivity demands of environmental labs working to EPA methodology such as 200.7 for the determination of metals and trace elements in water, solids and biosolids are met using synchronous dual view ICP-OES. The instrumentation achieves an excellent sample-to-sample cycle time of 58 seconds. This enables more samples to be measured each day and reduces argon consumption per sample by 50% per sample.
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.
