RestekSolidPhaseExtractionCartridges
ForCleanupof Environmental Samples
Solid phase extraction is one of themost widely used forms of sample preparation. Ease of use, safety, conser-
vative solvent usage, and cost effectiveness all contribute to its popularity.
We offer a range of SPE cartridges tomeet demanding cleanup procedures. Our standard products include
Florisil
®
sorbent, ion exchange resins, normal phasematerials, and bonded reversed phasematerials. In addi-
tion, we offer specialty products, including Florisil
®
in ultraclean glass tubes, mixed bed sorbents, and car-
tridges for specific applications. Our SPEmanifolds and pressure/vacuum pump, described in our chromatog-
raphy supplies catalog, will keep your system running efficiently.
Massachusetts TPH Cartridges
• Reduced background extractables.
• Easier quantification.
• Reproducible fractionation patterns, tube after
tube, lot after lot.
• Lower cost than glass tubes.
• Efficient processing on vacuummanifolds.
If you are seeing aromatic hydrocarbons in your
aliphatics fraction, use ourMassachusetts TPH silica
gel cartridges. We designed them specifically for sep-
arating aliphatic and aromatic hydrocarbons, to
meet the requirements of theMassachusettsmethod-

adsorbent is an excellent material for
cleanup of samples containing pesticides and/or
PCBs. In addition, it can be used to separatemix-
tures of aliphatic and aromatic hydrocarbons. An
