General description

Incorporates a phase consisting of a 2,6-di-O-pentyl-3-methoxy derivative of α-cyclodextrin. This phase is good for separations of heterocyclic amines. It has different selectivity from other phases and often shows reversal in elution from the PH phases. MAOT = 200 °C isothermal, 220 °C programmed.

Chem/Phys Resistance

Temp. Limits:
  • -10 °C to 200 °C isothermal, 220 °C programmed

Other Notes

We offer a variety of chromatography accessories including analytical syringes
