DB-XLB is exceptionally low bleed for active compounds, specifically pesticides, herbicides, PCBs, and PAHs, and for confirmation analyses.

• Exceptionally low bleed and low polarity; unique selectivity
• Excellent inertness for active compounds
• Ideal for confirmational analyses
• Excellent for pesticides, herbicides, PCBs and PAHs
• Ideal for GC/MS; MSD testing and certification available

The column delivers highly specific analysis of pesticides, herbicides, polychlorinated biphenyls (PCBs), and polyaromatic hydrocarbons (PAHs). DB-XLB is also excellent as a confirmation column for semivolatile environmental analyses.
