Restek Solid Phase Extraction Cartridges

For Cleanup of Environmental Samples

Solid phase extraction is one of the most 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 to meet demanding cleanup procedures. Our standard products include

Florisil

sorbent, ion exchange resins, normal phase materials, and bonded reversed phase materials. In addi-

tion, we offer specialty products, including Florisil

in ultraclean glass tubes, mixed bed sorbents, and car-

tridges for specific applications. Our SPE manifolds 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 vacuum manifolds.

If you are seeing aromatic hydrocarbons in your

aliphatics fraction, use our Massachusetts TPH silica

gel cartridges. We designed them specifically for sep-

arating aliphatic and aromatic hydrocarbons, to

meet the requirements of the Massachusetts method-

well. Capillary GC columns and reference materials

for the Massachusetts methodology are described in

request.

Florisil

Cartridges

Florisil

adsorbent is an excellent material for

cleanup of samples containing pesticides and/or

PCBs. In addition, it can be used to separate mix-

tures of aliphatic and aromatic hydrocarbons. An

effective cleanup procedure is summarized in

Application Note 59562A, available free on request.

Specialty Cartridges

Specifically designed to provide consistent and reproducible results for the listed method or application.

Polypropylene tubes with polyethylene frits.

Normal Phase Cartridges

Hydrophilic (polar) adsorbents used to extract hydrophilic analytes from nonpolar matrices, such as organic

solvents (e.g., polar contaminants from sample extracts). Polypropylene tubes with polyethylene frits, except as

indicated otherwise.

Massachusetts EPH/VPH/APH Methods

(lit. cat.# 59744)

Massachusetts’ gas chromatographic methods for

volatile (VPH), extractable (EPH), and air phase (APH)

fractions of gasoline and other petroleum products

have been adopted by other states, and in Canada. This

4-page publication lists many Restek products that can

help a laboratory meet the requirements of the

Massachusetts methods, including capillary columns

(Restek columns are specified in each method), extrac-

tion cartridges, analytical reference materials, and air

sampling canisters.
