FREESTYLE XANA PFAS
Based on the robust and established FREESTYLE XANA robotic system for large-volume water samples (0.1 L – 10 L), LCTech has developed a solution specifically for PFAS applications, in which plastics containing fluorine such as PTFE are avoided.

XANA for Automated SPE in PFAS Analysis
The column is firmly connected to the arm, therefore sample and solvent can be dosed precisely and at a constant flow rate via the SPE column with positive pressure using a syringe pump. Drying is also carried out via positive pressure with nitrogen.
- Non-stop Policy: If a column becomes blocked, the system detects the overpressure. The column is reset, the system cleans itself automatically and continues with the processing of the next column
- One rack for all types of columns: reusable adapters allow easy changing and mixing of columns of any standard format
- Columns can be moved to any position in the rack area
- Three solvents as standard, upgrade option up to six or even fifteen solvents
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:
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!
The sample rack offers space for 24 x 1 L sample bottles; optionally 3 sample containers with up to 10 L volume each can be connected to the system.
Automatic rinsing of the sample bottles possible for optimal quantitative transfer of the sample.
The vacuum concentrator D-EVA allows unattended, parallel and fast concentration of several samples with automatic stop at a defined volume between 10 and 150 µL.

Other Solutions for
PFAS Applications
LCTech developed robotic systems, especially for the sensitive PFAS application, almost completely free of plastics containing fluorine such as PTFE and thus offered a solution to the problem. It has not been possible to determine any blank values that come from the system.
The FREESTYLE PFAS system is available for 2 further FREESTYLE configurations:

Alongside large-volume water samples, the FREESTYLE PFAS system is also offered for samples with smaller volumes (without the XANA module): FREESTYLE SPE-PFAS
The SPE module can be used for all methods in the field of solid phase extraction. Through the controlled application of up to 4 bars of pressure, viscose samples or samples that do not contain solid suspended particles can also be pushed through the SPE column.
FREESTYLE SPE PFAS
With the FREESTYLE XANA PFAS TableTop, the automated clean-up of PFAS from a maximum of thirty water samples per sequence of up to 250 mL is possible quickly and without supervision, even at the weekend or overnight.
A high sample throughput per day can be achieved by interlacing individual, time-consuming process steps and processing up to 6 samples in parallel.
