Waters Corp Waters Sep-Pak Vac Cartridge, tC18, 3 cc, 500 mg Sorbent
This solid phase extraction cartridge features a silica-based bonded phase with strong hydrophobicity and trifunctional bonding chemistry, enhancing hydrolytic stability. It is designed for analyte isolation and enrichment from biological, environmental, and dietary samples, and is compatible with multi-position vacuum manifolds.
- Features a silica-based bonded phase with strong hydrophobicity.
- Offers trifunctional bonding chemistry for increased hydrolytic stability.
- Ideal for analyte isolation and enrichment from biological, environmental, and food samples.
- Simplifies protocols, minimizes sample handling, and helps avoid emulsion issues.
- Enhances safety by reducing exposure to hazardous agents and facilitating disposal.
- Supports direct field sampling, removing the need for sample transport to a lab.
- Constructed from high-grade, highly inert polypropylene.
Waters Corp Sep-Pak Alumina A 12 cc Vac Cartridge, 2 g Sorbent per Cartridge, 50 - 300 µm, 20/pk
Sep-Pak Alumina A Vac cartridges contain a highly active grade of alumina with an acidic 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 acidic alumina is also low-capacity ion exchanger in aqueous media. Unlike polymer-based ion exhangers, this sorbent is unaffected by high-energy radioactivity and can be used for radioactive compound isolation. These syringe-barrel-type cartridges are designed for use with vacuum manifolds and automated SPE instruments.
Waters Corp Vac Cartridge, Carbon Black/PSA Silica, 6 cc, 500 mg Sorbent
This vac cartridge features a two-layer sorbent bed designed for pesticide clean-up in food matrices prior to Gas Chromatography (GC) analysis. The PSA (Primary-Secondary Amine) sorbent provides alternative selectivity. It is a convenient, reproducible, disposable solid-phase extraction (SPE) device manufactured in an ISO 13485 and ISO 9002-registered facility, adhering to cGMP guidelines for Class 1 Medical Devices.
- Efficient pesticide clean-up in food matrices.
