Ultra 2

Standard Polysiloxane GC Columns

Agilent J&W Ultra 2 is a (5%-phenyl)-methylpolysiloxane, nonpolar column that resembles HP-5, but with tighter specifications for retention index and capacity factors. It has an operating temperature range of –60 to 325/350 °C and is intended for use with the Sadtler Retention Index Library. These precision-engineered columns are bonded, crosslinked, and solvent rinsable, and are tested to some of the strictest industry QC standards.
