Waters Corp Waters Sep-Pak Accell Plus QMA Classic Cartridge, 360 mg, 37-55 μm
Sep-Pak Accell Plus QMA Classic cartridges are silica-based, hydrophilic, strong anion-exchangers with large 300Å pores.
Waters Corp Certified Sep-Pak Vac Cartridge, Alumina N, 6 cc, 1 g, 50–300 μm
These Vac cartridges offer active alumina with neutral surface chemistry. The aluminum oxide surface provides polar analyte retention and Lewis acid properties. This normal phase sorbent is more stable than unfunctionalized silica under high pH, ideal for synthetic crude oil fractionation. Quality controlled for reproducible separations, they provide superior performance for ultra-low level analyte detection, reducing background interferences. Syringe-barrel-type for vacuum manifolds and automated SPE instruments.
