DB-5ht is a nonpolar column specially processed for an extended temperature limit of 400 °C.

• (5%-Phenyl)-methylpolysiloxane
• Non-polar
• Specially processed for extended temperature limit of 400 °C
• High temperature, polyimide-coated, fused silica tubing
• Excellent peak shape and faster elution times for high boilers

J&W DB-5ht nonpolar columns are manufactured from (5% phenyl) methylpolysiloxane. They deliver high levels of performance in a variety of analytical processes. High temperature limits of –60 to +400 °C result from precision engineered polyimide coated fused silica tubing. DB-5ht columns are also bonded, cross-linked, and solvent rinsable, and feature faster elution times for high boilers.
