SPE Disks and Cartridges
Waters Corp Waters Sep-Pak Cartridge, Alumina N, 6 cc, 1 g, 50 to 300 μm
Sep-Pak Alumina N Vac cartridges feature active alumina with neutral surface chemistry. Their aluminum oxide surface provides polar analyte retention and exhibits Lewis acid properties, offering stability greater than unfunctionalized silica under high pH. These syringe-barrel cartridges are ideal for synthetic crude oil fractionation and use with vacuum manifolds and automated SPE instruments.
- Facilitates easy sample extraction and transfer, minimizing spillage/loss.
- Provides a dependable chromatographic tool for enrichment/purification.
- Supports consistent positive-pressure flow with pumps/syringes.
- Compatible with vacuum-assisted flow devices and automated systems.
- Packaged in a non-contaminating poly-foil pouch for integrity and purity.
- Constructed from inert polypropylene to prevent analyte reactions.
- Operates efficiently across a wide pH range of 0 to 10.
Waters Corp Sep-Pak Aminopropyl (NH2) Plus Short Cartridge, 360 mg Sorbent per Cartridge, 55 - 105 µm, 50/pk
Sep-Pak Amino Propyl (NH2) Plus Short cartridges contain a moderately polar, silica-based bonded phase with weakly basic surface. The sorbent can be used as a polar sorbent with different selectivity for acidic/basic analytes or as a weak anion exchanges in aqueous medium below pH 8. Applications include extraction of phenols and phenolic pigments, petroleum fractionation, saccharides and drugs and metabolites. These versatile cartridges can attach easily to pumps and syringes for reliable, positive-pressure flow to speed up the sample processing time. They can also be fitted with removable reservoirs and used on vacuum-assisted flow devices and certain automated systems.
Hach Company ValuSep SPE Filter, 90 mm, 50/PK
ValuSep™ SPE Filters for EPA Method 1664A are designed to provide high recovery and low blank values in Horizon SPEDEX and SPE Manifold applications. Chemically treated with a proprietary reverse phase adsorbent, single layer borosilicate glass ValuSep™ SPE Filters (47mm) can filter the 40 mg/L EPA PAR standard in approximately 10 minutes with significantly faster filtration timesfor 1 L NPDES-type samples. ValuSep™ SPE Filters offer high recoveries and low blanks at a great price.
