Presentation Title: Total Fluorine Content Test Improvement and Standardization

Presentation Description: With the concern regrarding PFAS content in pulp molded and other products for oil and grease resistance, San Francisco and other municipalities have regulations limiting the total fluorine (F) content in foodservice packaging, especially those going to industrial compost facilities. F content can come from raw materials other than PFAS, e.g. talc mined in the presence of the common mineral fluorite. Thus, total F content determination does not definitively determine PFAS content and type.  However, total F content determination can determine whether the F content in a product must be further investigated to determine F contributor. A F content below detectable limits would ascertain that no PFAS (or other F containing chemical) is present.

Europe has a standard F content test method but literature has noted issues with the test.  Analytical labs in the US used their own variations of the test.  Unfortunately, it was found that test results varied between the labs. An effort was undertaken by Advanced Materials Center and this author to determine what the issues were and to determine a best practice.  The results of effort will be provided along with the practices needed to obtain precise and accurate results for total F content.

ASTM D20.70.01 Analytical Methods has been asked to prepare and approve the testing standard.
