Modern paints and varnishes are complex mixtures and the optimization of the material properties is an important task. One of the most essential variables is the curing which should in most cases take place in a reasonably short time span that can range from a fraction of a second to many days. It is difficult to evaluate the degree of the curing and its completeness by visual inspection. Therefore, an unbiased and reliable quantitative analysis is needed in quality control but also in R&D to optimize the varnish or the curing method respectively.
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?
