Agilent J&W DB-5ht nonpolar columns are manufactured from (5%-phenyl)-methylpolysiloxane. Bonded, crosslinked, and solvent rinsible, they deliver high levels of performance in a variety of analytical processes and feature faster elution times and excellent peak shape for high boilers. Precision engineered polyimide-coated fused silica tubing results in high temperature limits of –60 to 400 °C.
