Waters Corp Waters Sep-Pak Cartridge, DNPH-Silica, 800 mg, 55–105 μm, 20/pk
The Sep-Pak DNPH-Silica Plus Long Cartridge is designed for analyzing formaldehyde, other aldehydes, and ketones in air. It meets EPA Method TO-11A, JPM HLW, and ISO 16000 requirements, making it an excellent device for sample collection. Air is redirected through the cartridge using a vacuum pump, allowing ketones and aldehydes to react with DNPH, forming hydrazone derivatives. These hydrazones can then be eluted with acetonitrile for sample analysis.
- Provides low background for higher sensitivity.
- Saves time and increases productivity.
- Offers superior convenience and reproducibility, ideal for field sampling and process monitoring.
- Reduces solvent consumption, solvent exposure, and hazardous waste disposal costs.
- Supports high-speed, high-resolution UPLC Technology applications for excellent quantitation capability in the low parts-per-billion range.
Waters Corp Sep-Pak Alumina N 3 cc Vac RC Cartridge, 500 mg Sorbent per Cartridge, 50 - 300 µm, 50/pk
Sep-Pak Alumina N Vac RC cartridges contain a highly active grade of alumina with a neutral surface chemistry. The aluminum oxide surface provides an extremely polar surface for analyte retention and has properties of a Lewis acid. This normal phase sorbent is similar in use to silica; however, it is slightly more stable than unfunctionalized silica under high pH conditions. This neutral alumina is suitable for applications such as synthetic crude oil fractionation. These cartridges feature an integral 20 cc funnel-shaped reservoir for convenient processing of larger volumes of samples. They can be used with robotic sample preparation equipment or with vacuum manifolds.
Waters Corp Sep-Pak Aminopropyl (NH2) Plus Light Cartridge, 130 mg Sorbent, 55–105 μm
Sep-Pak Amino Propyl (NH2) Plus Light cartridges contain a moderately polar, silica-based bonded phase with a weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanger in aqueous medium below pH 8. Applications include the extraction of phenols and phenolic pigments, petroleum fractionation, saccharides, and drugs and metabolites.
- Finned outer body and reduced internal diameter for improved interstitial volume.
- Allows elution of fractions in minimal volume to improve recoveries and reduce solvent consumption.
- Sealed within a non-contaminating poly-foil pouch to maintain product integrity.
- Optimal particle size distribution, pore size, and surface area for uniform results.
Waters Corp Sep-Pak Vac Cartridge, Florisil, 5 g Sorbent, 20 cc Barrel, 50 to 200 μm

Waters Corp Waters Oasis MCX Vac Cartridge, 6 cc, 500 mg, 60 μm
These 6 cc cartridges utilize a novel, mixed-mode polymeric sorbent for optimal extraction of basic compounds via cation-exchange groups. The water-wettable sorbent maintains high retention and recoveries even if run dry, eliminating the need for special drying prevention steps. With a 60 μm particle size, they are ideal for viscous samples. Designed for vacuum manifolds and automated SPE instruments, these cartridges offer dual retention modes (ion exchange and reversed-phase) on a stable organic co-polymer from pH 0–14.
- Optimized for high selectivity in basic compound extraction.
- Water-wettable sorbent ensures high retention and recovery dry.
- Dual retention modes: ion exchange and reversed-phase.
- Clean, stable, high-surface-area organic co-polymer sorbent.
