SPE Disks and Cartridges
Waters Corp Waters Oasis Vac Cartridge, WAX/GCB, 6cc, 200/50 mg, 60 μm
This product is designed for environmental testing laboratories to perform low-level quantification of per- and polyfluoroalkyl substances (PFAS) in various environmental samples, including water, soil, and food. It features a combination of WAX and GCB in a single cartridge, streamlining the SPE process and saving time. Comprehensive quality control pre-screening for 32 PFAS prevents cross-contamination, ensuring accurate results and reducing false positives.
