Agilent J&W WAX GC columns

Enable a wide range of applications with our WAX column portfolio

WAX GC columns are ideal for diverse applications such as measuring free fatty acids and FAMEs, analyzing pyrolysis gasoline, and detecting smoke in wine.

Typically, using WAX columns at or above their maximum operating temperatures can damage the stationary phase, resulting in retention time stability issues. But now, an innovative WAX column technology overcomes this limitation.

Agilent J&W DB-HeavyWAX GC columns feature an extended temperature limit of up to 280 °C isothermal and 290 °C programmed.

These innovative columns deliver several advantages when analyzing difficult compounds:

  • The higher maximum temperature allows for shorter run times, plus a lower cost per test.
  • Reduced carryover minimizes the problem of ghost peaks.
  • Retention time stability and increased column lifetime.
  • Reliable column-to-column inertness.

DB-HeavyWAX columns are part of the Agilent WAX column portfolio for analyzing polar compounds.

Comparison of Retention Time Shift for o-Xylene

After 100 hours at 280 °C, WAX columns “A” and “B” showed a retention time shift of approximately two minutes. The Agilent J&W DB-HeavyWAX GC column remained consistent.
