Resprep PFAS SPE Cartridge, 6 mL, WAX 150 mg/GCB 50 mg, 30/pk

Resprep PFAS dual-bed cartridges provide a faster, simpler sample preparation workflow compared to using separate weak anion exchange (WAX) and carbon SPE cartridges. With both sorbents packed in the same cartridge, technicians can save time and reduce human error. Resprep PFAS cartridges are ideal for PFAS analysis of complex matrices, including non-potable water, solid, biosolid, and tissue samples using LC-MS/MS methods (e.g., EPA Method 1633). Our ultra-clean CarboPrep Plus carbon and PFAS-tested WAX sorbents ensure accurate trace-level reporting. Also available with a factory-packed, ready-to-use filter aid (catalog no. RK28931) that prevents clogging so that even dirty samples can be prepared in a single extraction. 

• Streamlined sample prep: WAX and CarboPrep Plus carbon sorbents are factory packed in a single dual-bed SPE cartridge for a faster, simpler workflow.
• Ultra-clean polymeric and carbon sorbents—every WAX lot is tested for Method 1633 PFAS to ensure method detection limits can be met.
• Compatible with both vacuum manifolds and automated systems.
