Thermo Fisher Scientific Helps Manufacturers with PFAS Testing


As government regulation of per- and polyfluoroalkyl substances ramps up worldwide, Thermo Fisher Scientific is seeing a boom in its PFAS testing business.

“We’ve seen an increase in demand from a number of countries in the Americas and in Europe,” said Toby Astill, director of environmental and food safety in chromatography and mass spectrometry at the life sciences giant. “Those regions are driving more discussions around current and future regulations than other regions.”

  • In recent weeks, the Environmental Protection Agency has issued several final rules concerning PFAS. These include the first-ever national regulation limiting PFAS in drinking water to near-zero levels and, just last week, the designation of two PFAS chemicals as hazardous substances under the Superfund law.

Writing is on the wall: Thermo Fisher foresaw the need for comprehensive PFAS analysis early on. That’s why it’s been offering clients a full suite of testing capabilities for more than a decade.

  • Commonly called “forever chemicals” because they do not break down easily in the environment, PFAS were used widely in everyday products starting in the 1940s, owing to their ability to put out fires and resist grease, corrosion and stains in addition to countless other consumer and industrial applications.
  • Using chromatography—“technology that allows lab users to separate and analyze the different components in samples,” according to Astill—Thermo Fisher can “confirm the presence of a specific substance and determine how much is there.”
  • The tech is not limited to PFAS, however; it can also detect, down to parts per trillion, the presence of pesticides, heavy metals and other substances, Astill said. And it works on samples of almost anything, including food packaging, water and even air.

Aiding compliance: In coming years, manufacturers may need to analyze their PFAS exposure comprehensively to remain compliant with Toxic Substances Control Act and other international regulations, including those from the EPA, Astill said.
