(nonpolarphase, Crossbond®100%dimethyl polysiloxane)
• General purpose columns for drugs of abuse, essential oils, hydrocarbons, pesticides, PCB congeners
or (e.g.)Aroclor®mixes, sulfur compounds, amines, solvent impurities, simulateddistillation, oxy-
genates, gasoline rangeorganics (GRO), refinery gases.
• Temperature range: -60°C to330/350°C (bleed tested temperature/maximumoperating temperature).
• Lowbleed - improved signal tonoise ratio, for better sensitivity andmass spectral integrity.
• Equivalent toUSPG2phase.
