How to Avoid Bias When Analyzing Ethylene Oxide in Air
Did you know you could be doing everything by the book for ethylene oxide analysis but still miss contaminants in air sampling canisters that can positively skew your results? This article explores potential sources of bias and offers strategies for mitigating it.
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.
Meet EPA 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.
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.
