App of the Month: IR Explainer

Chinese scientists recently made a surface-enhanced Raman scattering (SERS)-based approach to detect synthetic antioxidants in food samples.

Creating 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.

A recent study offers an inside look as to how chemometric modeling is directly impacting greener analytical solutions.

Metrohm has launched a website that details the use of portable Raman spectroscopy instrumentation to detect fentanyl, and other manufacturers are joining the battle too.

Metrohm considers NIR spectroscopy to be fast, easy to use, non-destructive, and chemical-free, and has developed a new addition to its platform for the analysis of liquid, solid, or a combination of samples in a short time.
