The FREESTYLE XANA PFAS TableTop is well-prepared for the requirements relating to PFAS. The analytical challenges are overcome by replacing all PTFE-containing components with blank value-free materials, such as PE and PP. This enables method-compliant sample processing according to US EPA standards (e.g. 537.1, 533, 1633) and DIN 38407-42 without producing blank values.
Large volumes are not absolutely necessary in order to analyse PFAS in water. As a result, the large bottle rack of the XANA is not needed in some cases. By downscaling the bottle rack, it can now be easily transferred to the FREESTYLE, saving a huge amount of space.
The column is firmly connected to the arm, so positive pressure from the syringe pump can be used to press sample and solvent over the SPE column in a very precise and controlled manner. Drying is also done by positive pressure via nitrogen.
The external processing station is responsible for the fluidics management of the water module with the pumping mechanics of up to 10 L samples, the valves and the sensor technology for process monitoring.
All components in the fluidic way ( tubes, valves, ...) are PTFE-free!
In the processing station on the FREESTYLE platform, 3 SPE columns are processed simultaneously in 2 blocks: In block 1, 3 columns are conditioned, loaded and washed in parallel, while in the following block 2, 3 columns are dried in parallel.
The following videos show the processing station of the FREESTYLE XANA. They are identical for all XANA models:
Thanks to its compact design, the XANA PFAS TableTop fits on a single laboratory bench. This allows you to organise your laboratory more effectively and efficiently and save valuable space and resources.
The robotic system works precisely and reliably, so you can even leave it running overnight to further optimise your workflow. It can be equipped with 2 sample racks, each offering 15 positions. This allows you to process up to 30 samples in a single sequence, saving a lot of time and effort.
With bottles for up to 250 mL sample volume, the Robotic System is perfectly suited for e.g. US EPA 537.1, 533 or 1633.
Via a special mechanism, Falcon tubes are also transferred into the processing station as eluate containers. This enables the elution solvent to be transferred efficiently and in a standard-compliant manner from the sample bottle into the Falcon tube via the SPE column.
