Agilent's precision-engineered DB-1ht columns deliver excellent performance in a range of GC/MS applications and are manufactured to the highest levels of quality and flexibility. Nonpolar DB-1ht columns are specially processed for operation within extended temperature limits up to 400 °C with optimised, polyimide-coated fused silica tubing. The bonded and cross-linked columns also deliver excellent peak shape and faster elution times for high boilers and are solvent rinsable.
