Palo Alto, CA -- Varian, Inc. (NasdaqGS: VARI) announced today the release of the VF-
5ht UltiMetal™ column for high temperature gas chromatography (GC), which is resistant to
damage under extreme operating conditions. These highly durable columns allow chemists to
confidently analyze samples at very high temperatures, up to 450 oC. Based on a stainless steel
capillary, Varian’s UltiMetal columns address several problems associated with fused silica
columns. A proprietary manufacturing process renders the steel inert and enhances the bonding
of the stationary phase. The result is long column lifetime with excellent peak shape and low
column bleed for the best detection limits at high temperatures. The UltiMetal column is a high
performance, lasting solution for high temperature gas chromatography
The columns have wide applicability in the separation of high boiling mixtures such as
long professional chain hydrocarbons, polymers, plastics, waxes, heavy polyaromatic hydrocarbons, tars,
triglycerides, motor oils, surfactants and crown ethers.
The VF-5ht UltiMetal column is the latest addition to Varian’s superb FactorFour range
of low bleed GC columns. FactorFour columns offer bleed specifications up to four times better
than alternative products. The columns are synthesized using a proprietary stabilization
technology that results in high signal-to-noise ratios for trace analysis, lower detector
contamination for reduced maintenance, better spectra, fewer background ions and faster
stabilization. In short, they provide better chromatography.
“Less column breakage results in savings for laboratories that analyze samples with high
temperature GC,” says Martin O'Donoghue, Senior Vice President, Scientific Instruments,
Varian, Inc. “Higher temperatures are often applied to speed up the analysis of high boiling
components and boost productivity. The VF-5ht UltiMetal column is the ideal solution for these
applications.”
