Testing Solutions for Metals and PFAS in Water
Author(s)Perkin Elmer
When 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.

Atomic spectroscopy has quietly gone from counting elements in bulk to counting single nanoparticles, imaging tissue at the micrometer scale, and reading Martian rocks from several meters away. The instruments got smaller, the software got smarter, and the questions they can now answer got a lot more interesting.
