How to Test Textiles for Total Organic Fluorine (TOF)

Total Organic Fluorine (TOF) testing of textiles helps determine whether the fabric in question contains fluorinated compounds. These may include PFAS chemicals used in stain- or water-resistant treatments. SimpleLab’s mail-to-lab Total Organic Fluorine Test for textiles provides certified laboratory analysis of total fluorine, fluoride, and organic fluorine content in one fabric sample.

How to Test Textiles for Total Organic Fluorine

Fluorinated compounds in fabrics and textiles, which includes cumulative or total PFAS content, can only be detected accurately through laboratory analysis. The SimpleLab TOF kit provides access to certified laboratories using validated analytical methods to quantify fluorine across organic and inorganic forms.

Each mail-to-lab kit includes:

All necessary sampling materials
Prepaid 2-day return shipping
Easy-to-follow instructions
Certified laboratory testing
Chain of custody documentation
Digital report with your results

Testing methodology at the laboratory includes the following broad chemical techniques to determine total fluorine levels in the sample provided:

Fluoride: Ion-Selective Electrode
Total Fluorine: Oxygen Flask Combustion and Ion-Selective Electrode
Total Organic Fluorine: Total Organic Fluorine by Ion Selective Electrode/Calculation

This approach gives a comprehensive picture of fluorinated content, including potential PFAS presence, in treated fabrics and textiles.

Who Is This Test Right For?

This test is designed for textile manufacturers, consumer product companies, environmental auditors, and anyone else who is looking to verify whether fabrics contain fluorinated compounds.

Typical uses include:

Assessing PFAS-free textile claims
Testing stain- or water-resistant fabrics
Evaluating clothing, upholstery, or gear for fluorine content
Supporting regulatory compliance efforts
Supply-chain or sustainability audits

Frequently Asked Questions

What does total organic fluorine (TOF) mean?

TOF refers to the total fluorine bound to organic compounds in a material. It serves as an indicator of fluorinated chemical presence, including all types of PFAS.

Is TOF testing the same as PFAS testing?

Not exactly. TOF testing provides a total measurement of fluorinated compounds rather than identifying specific PFAS molecules. It’s ideal for screening purposes.

Can DIY or strip tests measure fluorine in fabrics?

No. These compounds require professional analysis using specialized laboratory equipment. Only certified lab testing ensures accurate, trace-level results. DIY methods for fluorine analysis do not exist.

How long does the process take?

After the sample reaches the lab, you can expect results to be available within 10 business days.
