According to a recent study from Harvard University, the US EPA, and NIEHS, traditional targeted analysis techniques poorly characterize the PFAS composition of contemporary PFAS-based firefighting foams, know as aqueous film-forming foams (AFFF). Using the EPA 533 PFAS drinking water method for the analyte list, the researchers found that targeted mass spectrometry methods accounted for <1% of organic fluorine content. This is important because it demonstrates that targeted analysis methods miss nearly all the PFAS compounds in modern AFFF mixtures, thus underestimating the risk to human health and the environment.

Identifying the unknown PFAS profile in firefighting foams/AFFF
According to a recent study from Harvard University, the US EPA, and NIEHS, traditional targeted analysis techniques poorly characterize the PFAS composition of contemporary PFAS-based firefighting foams, know as aqueous film-forming foams (AFFF).

Is it raining PFAS?
It certainly is in the Great Lakes. According to raw data from the US EPA-Canada Great Lakes monitoring program, there has been a growing prevalence of per- and polyfluoroalkyl substances (PFAS) in rainwater in the Great Lakes basin.
The ugly truth about beauty products: PFAS in cosmetics
Scientists find signs of potentially dangerous “forever chemicals” in more than 100 popular makeup products
If you have ever wondered what gives long-lasting cosmetics their staying power, you may now have your answer. Scientists have found highly persistent, potentially harmful “forever chemicals”—known as per- and polyfluoroalkyl substances (PFAS)—in half of the cosmetic samples they tested in a new study published in June 2021.1
Mass spectrometer analysis gives you one more reason for taking a shower before swimming!

Should you bring your PFAS testing in-house?
As the per- and polyfluoroalkyl substances (PFAS) regulatory landscape evolves in the US and across the globe, the interest in PFAS continues to grow. Drinking water and food packaging are under particular scrutiny, and monitoring programs and requirements will continue to expand to include an increasing variety of sample types and PFAS compounds.
Using mass spectrometry to identify and quantify contaminants in water samples
Access to clean wholesome water is a basic human right. Humans have engineered incredible methods to collect, filter, purify, store and distribute water to billions of people worldwide, but does this mean that our water is completely safe to drink? Also, how do concentrations of water contaminants differ from source to source?
