The Effect of Heat Exposure on BPA and Phthalate Content in Commercial Bottled Water
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.
Poster Presentation - RISE imaging of various phases of SiC in sintered silicon-carbide ceramics
November 12th 2024In this poster presentation applications manager Ute Schmidt discusses the use of correlative Raman-SEM (RISE Microscopy) imaging for analyzing silicon-carbide (SiC) ceramics. The main focus of the work is investigating the distribution of sub-micron structured polytypes of SiC grains on and below the surface.
FT-IR gas analysis of coal-to-ethylene glycol process
October 31st 2024Coal-to-ethylene glycol is the process by which ethylene glycol is synthesized from coal instead of traditional methods using petroleum as the raw material. This study demonstrates that Fourier Transform Infrared Spectroscopy (FT-IR) can be a reliable alternative to simultaneously measure methyl nitrite and other process gases (such as CO and NO) using a single ABB analyzer.
