Waters Oasis WAX/GCB and GCB/WAX for PFAS Analysis cartridges

Wednesday, 27 March, 2024 | Supplied by: Waters Australia Pty Ltd


Waters has announced its Oasis WAX/GCB and GCB/WAX for PFAS Analysis cartridges, with design features that help streamline and expedite sample preparation and analysis of per- and polyfluoroalkyl substances (PFAS). The devices are QC-tested by an accredited laboratory for low residual PFAS, in order to reduce or eliminate any time spent troubleshooting potential assay contamination.

The dual-phase cartridges are designed to simplify and expedite the process of preparing complex samples, such as non-potable water, soil, biosolids and tissue. They replace a laborious and dirty two-step process to reduce sample prep and processing time while exceeding rigorous acceptance criteria.

The cartridges combine the two clean-up steps required under the US Environmental Protection Agency’s (EPA) Method 1633 for PFAS analysis — a weak anion-exchange (WAX) cartridge and dispersive solid phase extraction (dSPE) graphitised carbon black (GCB). They are designed to be faster and easier to use than the traditional method of using WAX and loose GCB, reducing the preparation process by approximately 30 min per sample batch. This allows users to eliminate additional manual steps in their workflow, including weighing out loose GCB, shaking, centrifugation and filtration.

The cartridges are designed to meet all EPA Method 1633 requirements for aqueous and solid samples. They are available in packs of 30 and 300 cartridges.
