PFAS are a diverse group of compounds resistant to heat, water, and oil. For decades, PFAS compounds have been used in hundreds of industrial applications and consumer products including carpeting, apparel, upholstery, food paper wrappings, fire-fighting foams, and metal plating. PFAS is referred to as the “forever chemical” as its contaminants can linger for decades.

PFAS chemicals are found in water, soil, waste, air, consumer products, and more. Pace® PFAS experts have experience working on a variety of PFAS sampling and testing projects in these areas and others:

Pace Analytical PFAS Testing and analysis


Through multiple PFAS lab locations, Pace® offers DoD- and EPA-approved test methods and others including Total Oxidizable Precursor (TOP) Assay and Total Organofluorine (TOF). The latter are used for the quantification of what are known to be thousands of additional non-targeted PFAS compounds, whereas targeted methods are currently limited to the identification and quantification of approximately 40 PFAS compounds.

Pace® Analytical True-TOF® Method

Pace® True-TOF® is a method used to quantify total organofluorine in a sample without extraction to a carbon media. With True-TOF®, we quantitate the total fluorine content and the total inorganic fluoride content using the same equipment. The subtraction of the two equals total organofluorine. Without the need for extraction, there is no need to be concerned about unrecovered compounds, so True-TOF® can be a more reliable test than the AOF method in many circumstances. True-TOF® is also a low volume test that only requires 10 mL of liquid matrix for easier sampling and with less waste.


In advance of EPA-issued PFAS regulations, many states and military bases have set their own PFAS testing and reporting requirements. And, in the wake of some recent -and staggering – financial settlements, many states are reducing reporting limits for industry and manufacturers. Our PFAS Regulations page offers several resources for you to learn more.

Pace® PFAS laboratories are certified and accredited for PFAS sampling, testing, and analysis. Our PFAS team actively monitors evolving State and Federal regulations to keep our clients informed. Stay current on regulatory and other PFAS issues by subscribing to our blog, PFAS Matters.


Pace® offers all the standard capabilities you would expect from a full-service lab including dedicated project management, sample services, and chain of custody documentation. But Pace® delivers more.
