Perfluorocarboxylic acids (PFCAs) are

anthropogenic organic compounds

with very unique and useful properties, e.g. surfactant properties and immense stability. These substances are nowadays widely used in many industrial and consumer products and summarized as micropollutants.

Their presence in human, biological and environmental samples throughout the world has been described in numerous research articles. Unfortunately, PFCAs have also been found to be toxic, persistent and bioaccumulative. Therefore, there is a great need for a constant and reliable detection of PFCAs in various matrices.
