Total fluorine testing measures the overall fluorine content present in a product or material and serves as a rapid screening tool for the potential presence of PFAS and other fluorinated compounds. This analysis helps manufacturers identify whether further, compound-specific PFAS testing may be necessary.
During the test, analysts convert all fluorine in the sample—both organic and inorganic—into a measurable form. The method commonly involves oxygen bomb combustion, followed by ion chromatography or ion-selective detection to quantify total fluorine. Because the test captures all sources of fluorine, it provides a conservative assessment of fluorinated content.
Manufacturers often use total fluorine testing as a first-step evaluation rather than testing for individual PFAS compounds immediately. When results show low or non-detectable fluorine levels, additional PFAS testing may not be required. However, elevated total fluorine results may indicate the need for targeted PFAS analysis.
This screening approach supports efficient decision-making during product development, reformulation, supplier qualification, and compliance reviews. Companies frequently apply the test to cosmetics, packaging materials, textiles, raw materials, coatings, and finished consumer goods. The method works well across solid, liquid, and semi-solid sample types.
Total fluorine testing also plays an important role in regulatory and sustainability initiatives. Many regions now restrict or monitor PFAS usage, and screening helps brands understand potential exposure risk early. Because the test does not identify specific PFAS compounds, it does not replace compound-specific analysis, but it does help prioritize follow-up actions.
This service is commonly used alongside PFAS Testing Services and broader Chemical Analysis Services to support environmental, regulatory, and product safety programs. Guidance for combustion-based fluorine determination is outlined in EN 14582, which is widely referenced for halogen content analysis.
Overall, total fluorine testing provides a fast, cost-effective way to screen for fluorinated substances, reduce unnecessary testing, and support responsible product stewardship.
