These general-purpose columns are designed for solvent impurities, PCB congeners, simulated distillation, drugs of abuse, gases, natural gas odorants, sulfur compounds, essential oils, hydrocarbons, semi-volatiles, pesticides, and oxygenates.

• Low bleed levels
• Longer column lifetime
• Short conditioning times

Columns exhibit long lifetimes and very low bleed at high operating temperatures. A proprietary synthesis process eliminates residual catalysts that could cause degradation and increase bleed. Phase composition: crossbonded 100% polydimethylpolysiloxane. Equivalent to USP G1, G2, and G38 phases.
