Analysis of PFAS in Textiles Based on EN 17681-1 and EN 17681-2

User Benefits

- Combining LCMS and GCMS enables the determination of PFAS below threshold limits in textiles. - Spike recovery test shows good percentage recoveries of all compounds (70–130 %) that are at or below the EU POPs threshold limit (25 ppb). - LabSolutions software offers integrated control over GCMS and LCMS for more efficient testing and data analysis.

Introduction

Per- and polyfluoroalkyl substances (PFAS) are used in a wide range of applications because of their useful properties, such as heat resistance and water repellency. However, PFAS are also extremely stable substances that resist degradation and accumulate in the environment, which has led to concerns about their effects on humans. Since eliminating sources of PFAS is essential to prevent them from accumulating in the environment and in living organisms, many countries are passing laws that restrict the production, distribution, and use of PFAS in products. For example, the EU POPs Regulation sets a permitted threshold of up to 0.025 mg/kg (25 ppb) for certain PFAS (including PFOA, PFOS, and PFHxS) in substances, mixtures, and products. EN 17681 is a European standard that describes methods for determining PFAS in textiles. The EN 17681 standard is divided into two parts according to the target compounds and methods. EN 17681-1 describes an LC/MS/MS method that targets ionic PFAS, and EN 17681-2 describes a GC/MS(/MS) method that targets certain semi-volatile and volatile neutral PFAS. A 2025 revision of EN 17681-1 changed the sample preparation method for more efficient PFAS extraction. This Application News describes the analysis of the target compounds shown in Table 1 based on the EN 17681-1 and EN 17681-2 standards, using both LC/MS/MS and GC/MS/MS.
