Sandra Wunsch, Application Specialist at Analytik Jena, gives us exciting insights into the analysis of bread for potassium bromate using spectroscopy and why the SPECORD PLUS is the best choice for this.

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.

Elena Hagemann, Product Manager for Process Spectroscopy at Metrohm USA, discusses a novel synchronized, automatic calibration data collector. This system eliminates the laborious calibration process of prediction model development without manual sampling. This capability allows moisture measurement systems to be calibrated at the factory down to approximately 7 ppm and to be installed in pipelines and reactors without additional calibration effort.

In this episode, Damon Strom from WITec’s marketing department, recounts how alphaCART, their portable, research-grade Raman system, joined the alpha300 line of production instruments. Listen to the podcast for a rare glimpse into the development process at Raman microscopy’s most innovative shop.

Bruker’s Surface Sensitive AFM-IR technology provides high-resolution surface sensitivity, reducing chemical probing depth to under 30 nanometers.

Purity is often viewed through the lens of the application or the chemist using a material. One level of purity can be good for a specific application and fail in another situation, making it a very relative benchmark. In this paper, we will discuss the importance of defining purity, impurities, and the situations in which high-purity inorganic raw materials are essential for analytical success.

As the threat of the opioid epidemic evolves and public health is put at risk, technology is an invaluable resource. Fortunately, libraries for handheld Raman spectroscopy can optimize the identification of bulk and near-bulk fentanyl.

For over a decade, Senior Product Scientist Derek Guenther has developed, tested and utilized Ocean Optics spectrometers for applications from reflectance of spacecraft metals to catching counterfeit Nike Air Jordans. In this episode, Derek shares insights on recent application challenges and the tools and techniques to take them on.

Dr. Derek Nowak discusses PiFM, an AFM-IR-based technique, to explain how IR spectroscopy and imaging can be extended to the nanoscale. With sub 5 nm lateral resolution and single-molecule-level sensitivity, PiFM opens up a wide variety of research avenues ranging from exploring nano-crystallin structures for drug delivery to process/failure analysis in semiconductor nanofabrication.
