WebPace® 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. WebIn Chapter 2, the occurrences of PFAS in North American cosmetics is shown through the measurement of elevated total fluorine concentrations in more than 50% of 231 cosmetic products analyzed. Targeted analysis results for select PFAS in 29 cosmetic products showed that all products contained detectable amounts of PFAS, at parts-per-billion and ...
WebFeb 11, 2024 · Analysis of PFAS is commonly performed using both targeted and nontargeted mass spectrometry methods. However, it has been demonstrated that measurements of fluorinated compounds in the environment by mass spectrometry often fall short of the total fluorine concentration.
