Waters Corporation Enhances PFAS Testing Efficiency With Oasis Dual-Phase Cartridges

Waters Corporation has recently unveiled its latest innovation in the field of environmental testing – the Oasis WAX/GCB and GCB/WAX Cartridges designed for the analysis of per- and polyfluoroalkyl substances (PFAS). This new product is set to revolutionize the way laboratories approach PFAS testing by significantly reducing both preparation and processing times. Specifically, these cartridges are engineered to cut sample preparation time by 20% and decrease sample processing duration by approximately 30 minutes per batch. This advancement not only enhances sample throughput but also offers substantial time and cost savings for laboratories.

The introduction of these cartridges comes at a pivotal moment. In 2023, legal settlements related to PFAS chemicals have exceeded $11 billion, highlighting the growing importance of accurate PFAS testing across various industries. Moreover, with major regulations on PFAS concentrations anticipated within the year, the ability to efficiently test for these substances is becoming increasingly critical for ensuring compliance.

The Oasis WAX/GCB and GCB/WAX Cartridges are meticulously QC-tested by an accredited laboratory to ensure low residual PFAS, thereby aiding in reducing potential assay contamination troubleshooting time. These cartridges ingeniously combine two essential clean-up steps mandated by the EPA's Method 1633 for PFAS analysis into one. By integrating a Weak Anion-Exchange (WAX) cartridge with dispersive solid phase extraction (dSPE) graphitized carbon black (GCB), they eliminate the need for additional manual procedures such as weighing, shaking, centrifugation, and filtration. This streamlined approach not only simplifies the process but also significantly enhances laboratory efficiency.

Amanda Cronin, a PFAS Laboratory Supervisor at Katahdin Analytical Services, has lauded the new cartridges for their time-saving capabilities and contribution to maintaining laboratory cleanliness. By consolidating multiple steps into a single cartridge, Waters Corporation's innovation facilitates improved operational efficiency and cost-effectiveness.

Compliant with all EPA Method 1633 requirements for both aqueous and solid samples, the Oasis WAX/GCB and GCB/WAX Cartridges are now globally available in packs of 30 and 300. This launch is part of Waters Corporation's broader commitment to providing comprehensive PFAS Testing Solutions in response to the surging demand for environmental testing of these substances.

As a global leader in analytical instruments and software, Waters Corporation specializes in chromatography, mass spectrometry, and thermal analysis innovations. With over 65 years of experience in the industry, the company operates across 35 countries and offers its products in more than 100 countries worldwide.
