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.
Testing Solutions for Metals and PFAS in Water
January 22nd 2025When it comes to water analysis, it can be challenging for labs to keep up with ever-changing testing regulations while also executing time-efficient, accurate, and risk-mitigating workflows. To ensure the safety of our water, there are a host of national and international regulators such as the US Environmental Protection Agency (EPA), World Health Organization (WHO), and the European Union (EU) that demand stringent testing methods for drinking water and wastewater. Those methods often call for fast implementation and lengthy processes, as well as high sensitivity and reliable instrumentation. This paper explains how your ICP-MS, ICP-OES, and LC-MS-MS workflows can be optimized for compliance with the latest requirements for water testing set by regulations like US EPA methods 200.8, 6010, 6020, and 537.1, along with ISO 17294-2. It will discuss the challenges faced by regulatory labs to meet requirements and present field-proven tips and tricks for simplified implementation and maximized uptime.
UV-Vis Spectroscopy: Exporting Your Measurement Out of the Instrument
January 20th 2025Optical fibers in ultraviolet-visible (UV-Vis) spectroscopy can enable measurements outside the traditional sample compartment. This paper details the components needed for fiber optic systems, such as couplers and probes, and reviews the performance of Agilent's Cary series instruments. It is crucial to choose the right fiber optic setup for a specific lab’s needs to ensure accurate and efficient measurements.
