SPE Disks and Cartridges
Waters Corp Waters Sep-Pak DNPH-Silica Cartridge, 350 mg, 55 to 105 μm
These cartridges are designed for analyzing formaldehyde, aldehydes, and ketones in air, meeting EPA Method TO-11A, JPM HLW, and ISO 16000 requirements. They trap these compounds by reacting them with DNPH to form stable hydrazone derivatives during sample collection.
- Analyzes formaldehyde, aldehydes, and ketones in air, meeting EPA TO-11A, JPM HLW, and ISO 16000.
- Utilizes vacuum pump for air sample collection and hydrazone derivative retention for HPLC/UPLC quantitation.
- Offers high-speed, high-resolution analysis for low parts-per-billion quantitation.
- Minimizes laboratory costs through reduced solvent consumption and hazardous waste disposal.
- Ideal for field sampling and process monitoring with >95% collection efficiency.
Waters Corp Waters Vac Cartridge, Oasis WAX, PFAS Analysis, 6 cc, 150 mg Sorbent
Waters Vac Cartridge, Oasis WAX, PFAS Analysis, 6 cc, 150 mg Sorbent
Waters Corp Waters Oasis Flangeless Vac Cartridge, WCX, 1 cc, 30 mg Sorbent, 30 μm
These flangeless vac cartridges feature Oasis WCX sorbent, a polymeric reversed-phase, weak ion exchange mixed-mode sorbent. They are optimized for fast, simple, and highly selective sample preparation of strong basic compounds and quaternary amines.
- Sorbent is water wettable, maintaining high retention and excellent recoveries even if dry.
- Eliminates the need for extraordinary steps to prevent sorbent beds from drying out during pre-sample loading.
- Flangeless configuration allows cartridges to be closely packed for processing in specialized automated SPE systems.
Waters Corp WATERS CORPORATION Oasis MCX Cartridge, 35 cc, 6 g Sorbent, 60 μm
Oasis MCX cartridges are designed for solid-phase extraction, featuring a mixed-mode cation exchange sorbent for bases. They are built upon a unique water-wettable Oasis HLB Copolymer, providing both reversed-phase and ion exchange modes of retention for enhanced performance.
- Functions as a mixed-mode cation exchange sorbent for bases.
- Constructed with water-wettable Oasis HLB Copolymer.
- Offers both reversed-phase and ion exchange retention capabilities.
- Ensures greater cleanup selectivity and sensitivity for basic compounds.
Waters Corp Sep-Pak Vac RC Cartridge, Aminopropyl (NH2), 20 cc, 500 mg, 55 - 105 μm
Sep-Pak Amino Propyl (NH2) Vac RC cartridges offer a moderately polar, silica-based bonded phase with a weakly basic surface. They can function as a polar sorbent for acidic/basic analytes or as a weak anion exchanger (below pH 8). Applications include extraction of phenols, saccharides, and drugs. These cartridges have an integral 20 cc funnel-shaped reservoir for larger samples and are compatible with robotic systems or vacuum manifolds.
- Moderately polar, silica-based bonded phase with weakly basic surface.
- 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.
- Integral 20 cc funnel-shaped reservoir for convenient processing of larger volumes of samples.
- Can be used with robotic sample preparation equipment or with vacuum manifolds.
