• General purpose columns for drugs of abuse, essential oils, hydrocarbons, pesticides, PCB congeners or (e.g.) Aroclor® mixes, sulfur compounds, amines, solvent impurities, simulated distillation, oxygenates, gasoline range organics (GRO), refinery gases.
• Ultra-low bleed - improved signal to noise ratio, for better sensitivity and mass spectral integrity.
• Temperature range: -60°C to 330/350°C (bleed tested temperature/maximum operating temperature).
• Equivalent to USP G2 phase.
