“Among themostwidelyused capillary columns todayare the
polar polyethylene glycol (PEG) columns. While PEG columns
offer a unique selectivity for awide variety of analyses, their
uses have been limited because of short column lifetimes, re-
stricted operating ranges, and poor inertness.
RestekCorporationhasbeenprovidingchromatographerswith
superior capillary columns since 1985. And, our PEG columns are just another ex-
ample of howwe’ve improved on existing technology to solve customers’ problems.
The columns in thisguidearedurable, functionat awide rangeof temperatures, and
are highly inert.
We have designed six different PEG capillary GC column phases — Stabilwax

each an innovative improvement over existing, competitor PEG columns. In addition
to the wide variety of PEG columns, we offer many custom column materials and
configurations.Wewill try tomatchany columnwritten intoamethod, or engineer a
