High-Resolution Chemical Imaging with Tapping AFM-IR
Tapping AFM-IR combines IR spectroscopy and AFM topography mapping to overcome traditional resolution and sample-type limitations to a host of new applications.
The Effect of Heat Exposure on BPA and Phthalate Content in Commercial Bottled Water
May 8th 2024This 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.
Spex Speaks Science: Soil and Contamination
May 8th 2024The science and art of gardening and agriculture is part passion, part luck and a lot of chemistry. In this podcast, we will take a look at the science of soil and how chemistry can affect the growth and health of plants. We will also take a look at sources of potential contamination in gardens and how those contaminants can be tested and remediated. Hosted by Patricia Atkins, Manager, Global Product at Spex®.
The Analysis of Laboratory and Consumer Water Sources for the Presence of BPA and Phthalates
May 8th 2024Bottled water has evolved from a trendy luxury to a global consumer staple, with significant growth projected by 2012. In the U.S., consumption has soared, with safety concerns and substitution driving its popularity. Developing nations also rely on bottled water for safety. This study aims to address debated issues surrounding BPA and phthalate exposure in consumer water sources: 1. Are BPA and phthalates present in bottled water? 2. Does exposure to high temperatures increase leaching of BPA or phthalates? 3. Are levels in municipal or filtered water significantly different from bottled water?
