The VF-5ht UltiMetal column is the latest addition to Varian’s respected FactorFour™ range of low bleed GC columns. FactorFour columns are superior GC capillaries offering bleed specifications up to four times lower than competitive products. The columns are synthesized using a proprietary stabilization technology that results in the highest 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 greatly improved chromatography.
The VF-Sht UltiMetal column is a robust gas chromatography capillary designed for high-temperature applications. It features an UltiMetal coated stainless steel construction that provides superior inertness compared to traditional fused silica columns with polyimide coatings, which can degrade above 350 °C.
Key benefits include extreme durability against breakage, stabilized liquid phase coating for low bleed and excellent trace analysis, and the ability to withstand long-term high-temperature use. The column offers improved peak shapes and reduced maintenance costs due to its resistance to damage.
Temperatures above 350 °C degrade the coating and reduce physical strength.
The column was used with a temperature range of 50 °C to 400°C.
The column is 30 m long, has an inner diameter of 0.25 mm, and a film thickness of 0.1 um.
