CP-Sil™ Columns

The CP-Sil line consists of a range of stationary phases which are based on a polysiloxane backbone. Functional groups are added to the polymer to introduce selectivity. Each polymer
used for the CP-Sil line is manufactured in-house and is optimized to obtain highest degree of reproducibility. The CP-Sil includes chemical bonded, non-chemical bonded and ms-type phases.
Chemically bonded phases have a high stability and durability. As the stationary phase is
chemically bonded to the fused silica surface, it can withstand direct (liquid) solvent injections,
and in case of contamination, columns can be rinsed with solvents to extend column life.

EZ-GRIP™
All capillary columns from Varian are standard outfitted with
EZ-GRIP™ for enhanced ease-of-use. Varian’s EZ-GRIP™ capillary column cage makes installation, coupling and operation of capillary columns user-friendly, less time consuming and also improve reliability for the method.

Guaranteed Quality
Varian GC columns are manufactured under close supervision and to exact specifications. A final quality assurance test ensures that every GC column shipped meets our tight specifications, published in the test report supplied with each GC column.
