PFAS (Per- and Polyfluoroalkyl Substances) Testing Services
PFAS (Perfluoroalkyl and Polyfluoroalkyl Substances) testing is done to detect the concentration of PFAS in a product. PFAS are a complex group of produced chemicals that are used as ingredients in several everyday products. These chemicals are very stable as a result of the strong chemical bonds between the carbon and multiple fluorine atoms.

PFAS Testing Methods – Overview
PFAS (Perfluoroalkyl and Polyfluoroalkyl Substances) Testing evaluates the presence, concentration, and distribution of persistent fluorinated compounds in various materials and environmental samples. These substances are chemically stable and resistant to degradation, making accurate detection critical for safety and regulatory compliance.
The testing involves advanced analytical techniques such as chromatography and mass spectrometry to identify trace-level contaminants. It supports risk assessment, contamination monitoring, and regulatory validation by quantifying individual PFAS compounds and total fluorine content across different sample matrices.

Frequently Asked Questions
PFAS compounds are highly stable, exist at very low concentrations, and often occur as complex mixtures. Their chemical diversity requires sensitive analytical techniques and careful sample preparation to achieve accurate and reliable detection.
Even very low concentrations of PFAS can pose environmental and health risks, making high-sensitivity detection essential for accurate risk assessment and regulatory compliance.
Targeted analysis measures specific known PFAS compounds, while non-targeted analysis identifies unknown or emerging compounds, providing a more comprehensive assessment.
Solid-phase extraction concentrates PFAS from large sample volumes and removes interfering substances, significantly improving detection sensitivity and analytical accuracy in complex environmental matrices.
Mass spectrometry identifies compounds based on unique mass-to-charge ratios and fragmentation patterns, allowing differentiation between closely related PFAS compounds even at very low concentrations.
