The concerns regarding per- and polyfluoroalkyl substances (PFAS) continue to grow. In response, regulations continue to impose restrictions on PFAS, a group of thousands of manmade chemicals, and not just individual species of PFAS like perfluorooctanoic acid (PFOA) or perfluorooctane sulfonate (PFOS). As a result, PFAS analytical techniques that only look for a handful of specific PFAS species may not be sufficient in determining PFAS contamination.

Dyne is pleased to announce our recent investment in Metrohm’s new, state-of-the-art fluorine analyzer: the ProfilerF. The ProfilerF can determine true total fluorine content. By subtracting the free fluoride (fluoride found in ionic form in solution) from the total fluorine result, you are left with a total organic fluorine concentration (the fluorine found attached to organic compounds, i.e. PFAS). Dyne is able to determine fluorine content in both firefighting foam and system water samples with a quantification limit of 1 part per million (ppm).

Why use Dyne Fire Protection Labs for your Total PFAS Analysis via TOF?

  • free shipping within the contiguous United States (limited free 1-way shipping to Alaska, Hawaii, Puerto Rico, and Canada, inquire for details)

  • test reports in 5-business days guaranteed

  • clear, concise reports

  • online access to results and forms

  • immediate communication with our chemists or support staff

PFAS Analysis Method

Pros

Cons

Speciated Approach via LC

(Dyne does NOT offer this analysis)*

Low detection limits (ppt) are possible

Can quantify specific PFAS species (i.e. PFOA, PFOS, etc.)

Does not account for all PFAS species

Total Organic Fluorine (TOF) via CIC

(Dyne offers this analysis)

Accounts for all PFAS species

Low detection limits (ppt) are NOT currently possible

Can NOT quantify specific PFAS species (i.e. PFOA, PFOS, etc.)
