FREESTYLE XANA PFAS

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.
