In advanced laboratories, various analytical methods are applied to determine the concentration of precursor compounds in samples, including PFAS (perfluoroalkyl substances) analyses . Approximately 30 distinct PFAS compounds are qualitatively and quantitatively identified in a perfluoroalkyl substances (PFAS) analysis. The TOP assay is an oxidative preparation analytical method that measures the concentrations of precursors that can decompose into more persistent perfluoroalkyl sulfonates and perfluoroalkyl carboxylates.

Perfluoroalkyl substances (PFAS) are a class of synthetic compounds widely used in industrial applications characterized by a highly fluorinated hydrophobic linear carbon chain attached to a hydrophilic functional group. These compounds attract attention due to their extreme persistence in the environment, their ability to bioaccumulate, their potential for toxicity, and their adverse effects on human health.
The chemical nature of these compounds gives them unique properties such as thermal stability and the ability to repel water and oil, making them useful in a wide variety of industrial and consumer products. For example, fabric stain protectors, fabric waterproofing, non-stick cookware, food packaging, lubricants, fire extinguishing foams.
Perfluorooctanoic acid and perfluorooctane sulfonate are two of the best known and most used perfluoroalkyl substances (PFAS). During the production process of some perfluoroalkyl substances and the use of PFAS products, perfluorooctanoic acid and perfluorooctane sulfonate are released into the air, water and soil. In addition, these chemicals can be transported over long distances.
Other environmental perfluoroalkyl substances include perfluorooctane sulfonamides, sulfonamidoethanols, fluorotelomer sulfonates, and other forms of perfluorocarboxylate and perfluorosulfonate. The American Environmental Protection Agency (EPA) has identified evidence that perfluorooctanoic acid and perfluorooctane sulfonate can cause cancer. In addition, the World Health Organization (WHO) has found that perfluorooctanoic acid is possibly carcinogenic to humans. The EPA has a drinking water health recommendation of 70 parts per trillion for perfluorooctanoic acid and perfluorooctane sulfonate concentrations. Above these levels, steps need to be taken to assess contamination of drinking water systems, inform consumers, and limit exposure.
Our organization also provides PFAS (perfluoroalkyl substances) analysis testing services with its trained and expert staff and advanced technological equipment, among the numerous test, measurement, analysis and evaluation studies it provides for businesses in various sectors.
