Answer:It is a high-polarity polyethylene glycol-type GC stationary phase.
Answer:It reduces active-surface interactions that can cause peak tailing or analyte loss.
Answer:The operating-temperature range is 20 °C to 230/240 °C.
Agilent J&W DB-WAX Ultra Inert is a highly polar fused-silica GC capillary column with a polyethylene glycol-type phase and deactivated surface for sensitive analysis of oxygenated or otherwise active volatile analytes. The 30 m column has a 0.53 mm inner diameter and a 1.00 µm bonded stationary-phase film, and it is supplied in a 7-inch cage. The ultra-inert treatment helps reduce unwanted adsorption that can distort peaks for challenging compounds. Its specified temperature range is 20 °C to 230/240 °C, which differs markedly from the temperature limits of many low-polarity polysiloxane GC columns.
