Total Fluorine Screening

Chemical Identification

The test uses combustion ion chromatography to burn the fabric sample and capture the resulting fluorine gas in a liquid solution. This solution is analyzed to determine the total concentration of fluorine in parts per million. If the level is high, it is highly likely that the fabric was treated with persistent fluorinated compounds.

Border Screening

Regulators and brands use this rapid test to sort compliant water-repellent clothing from non-compliant stocks quickly. This preliminary filter saves time and reduces the cost of chemical testing for large garment shipments. Any sample that exceeds the screen limit is sent for full chromatographic analysis.

Verification Method

Finishing plants that produce outdoor apparel use this test to prove that their water repellents are free of contamination. Screen testing prevents chemical compliance failures.
