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.

The United States Food and Drug Administration (FDA) is using Remote Interactive Evaluations (RIE) to assess regulatory compliance, review submission material, or determine the timing of future inspections. Here, we look at some of the impacts of RIE on GxP laboratories. Although RIE is voluntary, is this an offer that you cannot refuse?

This study aimed to assess the levels of phthalates and bisphenol A (BPA) in various popular bottled waters compared to tap water. Additionally, it investigated whether exposure to high temperatures, akin to those in a car during summer, would elevate these levels. Using GC/MS analysis, samples were examined. Results showed that phthalates and BPA were either absent or well below safety thresholds in all bottled and tap water samples. Moreover, heating did not significantly affect phthalate concentrations, and BPA was undetectable in all samples.
