Agilent DB-HeavyWax GC Columns

J&W DB-HeavyWAX Polyethylene Glycol (PEG) is a high-temperature WAX GC column that can operate at higher maximum temperatures (280°C isothermal, 290°C programmed) than standard WAX columns. This allows for shorter run times, providing a lower cost per test. The GC column provides retention time stability and increased column lifetime, even when used at maximum operating temperature.

The ability to bake out the column at the end of the analysis reduces sample matrix effects, limiting carryover and the risk of ghost peaks. The column also exhibits very low bleed, which results in better signal-to-noise ratios and lower detection limits (LOD), especially for late-eluting compounds.

The DB-HeavyWAX column phase is also available in columns designed for Intuvo 9000 GC systems.
