Collecting high-quality soil gas samples in the field for TO-15 analysis is essential for generating reliable data. Yet in the field, the process can be time-consuming and prone to error. With our clients’ sampling challenges in mind, Merit Laboratories designed a helium shroud that makes soil gas sampling more efficient, accurate, and reproducible — without the need for tools or field calibration.
We’re excited to announce that Merit Laboratories will be participating in the conference, taking place August 4th - 7th, 2025, in St. Louis, Missouri. This year’s conference theme, “Building a Quality Culture as the Foundation for Reliable Data,” underscores the importance of quality assurance and continuous improvement in environmental monitoring and measurement.
Have you ever reviewed a laboratory report and felt overwhelmed by acronyms like MDL, RL, LOQ, or IDL? You’re not alone. These terms are critical to understanding the sensitivity, precision, and reliability of laboratory results in environmental testing—but they can also be confusing, especially when used interchangeably or inconsistently across different labs or agencies.
The U.S. EPA released a Draft Sewage Sludge Risk Assessment for PFOA and PFOS, open for public comment. The public comment for the draft, released in January 2025, has been extended until August 14, 2025. This draft risk assessment reflects the EPA's latest scientific understanding of the potential risks to human health
To all of our friends and partners in California impacted by the devastating wildfires, Merit Laboratories is here to support you. When wildfires ravage communities, natural landscape, and places we call home, the impact is major. Lives are interrupted while homes, schools, and businesses are destroyed. Another significant impact of wildfires is environmental contamination.

The term summa canister is trying to go the way of other product names that have become generic titles for their intended purpose, like Kleenex and Band Aids. The term summa canister is used in the environmental industry by many professionals to describe the sampling media used for air sampling prior to laboratory testing. There is, however, inherent risk in believing that summa canister is an acceptable term that defines all air sampling media for TO-15 projects.
