Agilent's J&W DB-HT Simulated Distillation GC columns feature a 'boiling point' phase for high temperature simulated distillation, and durable stainless steel tubing for consistently excellent performance. These low bleed columns have a distillation range of C₆ to C₁₁₀ with an operating temperature range of -60 to 430°C. The columns are bonded, cross-linked, and solvent rinsable, and are rigorously tested to some of the strictest industry QC standards to ensure accurate results.
