Fused Silica Capillary Column are produced with the industry standard polyimide outer coating (390° c maximum temperature) for most general GC applications. Columns with high temperature polyimide coatings, for applications 400° C, are available upon request.

The inertness of Ultra ALLOY stainless steel columns matches that of fused silica and is derived from a patented, multi-step manufacturing process which utilizes a five-layered pre-treatment of the inner surface of the stainless steel.
• High temperature stability
• Highly inert deactivated inner surface
