Expansion of PFC Scope and Better Limits of Quantification
Method Optimisation Offers an All-round Service for the Analysis of PFC
August 2018. Perflourinated compounds show a high thermal and chemical stability as well as water-, fat- and dirt- repellant properties. Due to these specific properties, per- and polyfluorinated compounds are widely used in many industrial and consumer products since a couple of years. More than 300 substances belong to the artificially produced group of compounds, which are utilised significantly in impregnating agents, fire extinguishing foams and lubricants or for instance in the production of Teflon. All share the property to be neither decomposed by natural processes nor in sewage plants, therefore the ubiquitous distributed PFC accumulate in the environment and all organisms. Moreover, the suspicion that many PFC are carcinogenic is widely acknowledged and turns the spotlight more often to their analysis.
Shortened TAT, More Sensitive Limits of Quantification, Extended Scope of Parameters and Matrices
GfA Lab Service guarantees a processing time of 48 hours for drinking and sewage water. In addition, the laboratory is able to analyse PFC in food, feed and biota.
From September 2018 on, the GfA Lab Service expands its previous scope of analysis of PFC. A crucial element during the method revision was the implementation of methylated and ethylated PFC. The limits of quantification could be lowered by up to 33% (see table below).
