Automated determination of PFAS
Automated PFAS purification with minimized blank values
A well-known challenge in the analysis of perfluoroalkyl and polyfluoroalkyl substances (PFAS) are too high blank values and therefore falsified results. These arise from the material used in purification and measuring systems, since the fluorine-containing plastics that are often used can release PFAS.
LCTech has almost completely freed fluorine-containing plastics such as PTFE from a robotic system, especially for the sensitive PFAS application, and thus the solution to the problem. No blank values originating from the system could be determined.
The FREESTYLE-PFAS system is available for 2 FREESTYLE configurations:
- FREESTYLE BASIC system with SPE and XANA module for high-throughput water analysis
- FREESTYLE BASIC system with SPE module
Automated determination of PFAS in 0.05 – 10 L water samples
With FREESTYLE XANA-PFAS, the automated purification of perfluoroalkyl and polyfluoroalkyl substances from up to 24 water samples from 0.05 to 10 liters is possible quickly and without supervision, even on weekends and overnight. By parallelizing the individual process steps “conditioning”, “loading”, “washing” and the simultaneous processing of 3 samples each, a high sample throughput per day is managed.

Automated determination of PFAS in up to 100 mL samples using SPE
In addition to large-volume water samples, the PFAS system is also available for samples from solid-phase extraction with smaller volumes (without XANA module): FREESTYLE SPE-PFAS. The SPE module can be used for all methods in the field of solid phase extraction. Controlled pressurization of up to 4 bar means that viscous samples or samples that do not contain solid suspended matter can also be pressed through the SPE column.

Perfluoroalkyl and polyfluoroalkyl substances
| PFAS can be found in a variety of our everyday objects and materials. Among other things, they are used for grease and water-repellent surfaces in the textile and paper industry, but also for cleaning agents, paints, waxes or paints. PFAS find a very special area of application due to their thermal stability in fire extinguishing foams.

They are released into the environment during the manufacturing process, but also during use or disposal. PFAS can therefore be detected worldwide in the environment, in wild animals or in human tissue and blood. The substances are already detected even in polar regions.
PFAS are anthropogenic and are characterized by extreme persistence. It is still not entirely clear what effects PFAS have on the human body or what concentration has to be reached in order to have an effect.
