SPE Disks and Cartridges
Waters Corp Waters Oasis Method Development Sorbent Selection Kit, 1 cc, 30 mg, 30 μm
This sorbent selection cartridge kit is designed for rapid development of Solid Phase Extraction (SPE) methods for LC/MS analysis. It offers both reversed-phase and ion exchange modes of retention for cleanup selectivity and sensitivity for acidic and/or basic compounds. The kit contains 40 cartridges, with 10 each of MAX, WAX, MCX, and WCX mixed-mode, ion-exchange chemistries.
- Rapidly develop SPE methods for LC/MS analysis.
- Includes 40 cartridges (10 each of MAX, WAX, MCX, WCX).
- MAX is a strong anion exchanger for acids.
- WAX is a weak anion exchanger for strong acidic compounds.
- MCX is a strong cation exchanger for bases.
- WCX is a weak cation exchanger for strong bases and quaternary amines.
- Water wettable sorbents maintain retention and recovery even if they run dry.
- No need for extra safety measures to prevent sorbent beds from drying out.
Waters Corp Oasis MAX Flangeless Vac Cartridge 3 cc, 60 mg, 60 μm
Oasis MAX 3 cc Flangeless Vac Cartridges utilize a novel, mixed-mode polymeric sorbent for high selectivity and sensitivity in extracting acidic compounds. The water-wettable sorbent ensures high retention and excellent recoveries even if dry, removing the need for special precautions. Its flangeless design allows for close packing in automated SPE systems and it supports a 0–14 pH range.
- Optimized for high selectivity and sensitivity in extracting acidic compounds with anion-exchange groups.
- Water-wettable sorbent maintains high retention and excellent recoveries even if it runs dry.
- Flangeless configuration enables close packing for automated SPE systems.
- Separates acidic and basic/neutral chemicals and effectively removes phospholipids and lysophospholipids.
- 60 μm particle size is recommended for viscous samples.
- Each pack contains 100 cartridges.
Waters Corp Sep-Pak Accell Plus CM 20 cc Vac Cartridge, 5 g Sorbent per Cartridge, 37 - 55 µm, 20/pk
Sep-Pak Accell Plus CM Vac cartridges contain a silica-based, hydrophilic weak cation-exchanger with large pore size (300Å). The cartridges are designed for extraction of cationic analytes in aqueous and non-aqueous solutions. The large pore size makes it ideal for isolation of molecules such as cationic proteins. Other applications include extraction of steriods, pesticides, and herbicides. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
