These columns are recommended for semivolatiles, halogenated compounds, pesticides, herbicides, drugs of abuse, amines, unknown sample screening.

• Excellent for trace level analysis of acids and bases, such as semivolatiles analysis
• Specifically tested for inertness for active compounds including acidic and basic compounds
• Improved signal-to-noise ratio for better sensitivity and mass spectral integrity
• Non-polar with very low bleed characteristics, ideal for GC/MS
• Bonded, cross-linked and solvent rinsable
