Meet evolving PFAS regulations with automated, high-throughput workflows, from sample preparation to analysis and detection, using SPE, EOF, and AOF workflows.

- High-throughput via automation
- Reliable trace-level analysis
- Solution for complex matrix + experts for advice
- Automation cut manual workload significantly
- Up-to-date compliance-ready solutions

PFAS monitoring is becoming more demanding, with stricter limits, broader compound lists, and increasing testing pressure. We spoke with Roel Kwanten from Rijkswaterstaat about regulatory trends and the growing impact on laboratories.
Laboratories need a robust analytical workflow to quantify known PFAS and screen for unknown PFAS across a wide range of aqueous matrices. Velaris automated workflows are built to handle even the most complex samples while maintaining high throughput, enabling laboratories to achieve accurate, reliable, and efficient PFAS analysis.

Combine SPE, EOF, and AOF workflows to efficiently meet PFAS regulations, increase throughput, and ensure trace-level analysis.
Common automated sample preparation solutions, including extraction/cleanup and evaporation steps, can be used for both target PFAS analysis and EOF screening.

The SPE-03 automated SPE system processes up to 8 samples in parallel, with flexible bottle mounting for sample volumes from 0.5 to 4000 mL, built for high-throughput extraction across complex matrices.
High Capacity Inline Filter (F-HC-30)
A high-capacity inline filter designed to remove both fine and large particulates. Suitable for processing up to 1 L of drinking water, surface water, or wastewater.
PFAS-specific SPE cartridges optimised for seamless integration with SPE03 automation. Designed to provide robust PFAS enrichment, cleanup, and recovery while supporting compliance with major regulatory methods and standards
Anti-Clogging Cartridge Frits (CF-06 or CF-03)
Multi-layer frits are installed on top of the SPE cartridge, before extraction, to reduce the likelihood of cartridge clogging when processing challenging matrices.
The vacuum concentrator D-EVA allows unattended, parallel and rapid concentration of up to 53 PFAS samples with automatic stop at a defined end-volume between (e.g. 500 – 900 µL). The quantitative transfer into a GC vial is possible without time-consuming rinsing of the sample vessel.
Combustion unit connected to Ion Chromatography. Pyrohydrolitic combustion of the extracted liquid containing PFAS. The formed HF is absorbed with UPW in a fraction vial. These negatively charged ions, will be injected and separated in the IC column.
AOF (Adsorbable Organic Fluorine) analysis for PFAS screening.

Autosampler designed for accurate, rapid and easy sample preparation of samples that require sample pretreatment for AOX/TOX and AOF analyses according to the column method (EPA 1621).
The water samples automatically pass through the columns, where organically bound halogens were adsorbed onto microcolumns filled with activated carbon.
The Xprep-A6 serves as a stand-alone system for preparing samples for AOF analyses, which can be carried out by the Xprep C-IC.
These microcolumns were then placed into the Tuscan autosampler, which introduced them into the Xprep C-IC sample boat.
The activated carbon is combusted in an oxygen-rich environment at high temperature. After combustion, the output gas stream containing the analytes is transferred to the Fraction Collection Unit and trapped in the absorber solution.
No additional autosampler is required, as the fraction collection unit of the Xprep C-IC also functions as an autosampler for the IC. It allows the collection and storage of up to 65 combusted samples.
