A Methods-Based Guide to Laboratory Supplies for PFAS Testing
PFAS are ubiquitous in the environment and can even be found in laboratory equipment. Using high-quality lab supplies is essential for accurately monitoring these pervasive contaminants. This methods-based reference guide makes it easy to find the products you need for commonly used ASTM, DIN, EPA, and ISO methods.
Meet Method 537.1 PFAS Requirements with a Contaminant-Free Workflow
This application note demonstrates a contaminant-free workflow for EPA Method 537.1 PFAS analysis. As shown here, no background interferences were present and good recoveries were obtained for all target analytes. Use of clean, contaminant-free supplies results in reliable system qualification and more accurate reporting.
Best Practices for TO-15A Samplers, Air Canisters, and Analytical Systems
When collecting and analyzing whole air samples, it is critical to ensure that your entire system is as clean and inert as possible. In this article, we walk through Method TO-15A requirements, guidelines, and best practices to ensure equipment is clean, inert, and properly qualified so you get accurate, reliable results.
Same Procedure, Better Cleanup—Change Doesn’t Get Easier Than That!
CarboPrep Plus SPE cartridges use the same solvents, volumes, and manifolds as a standard Florisil method, but the difference in cleanup is clear. CarboPrep Plus SPE does a much better job of removing matrix components, so with the same procedure you get cleaner sample extracts and less downtime for maintenance.
