DB-XlB

• Exceptionally low bleed
• Low polarity
• Extended temperature limit of 340/360 °C
• Unique selectivity
• Excellent inertness for active compounds
• Ideal for confirmational analyses
• Excellent for pesticides, herbicides, PCBs and PAHs
• Ideal for GC/MS
• Bonded and cross-linked
• Solvent rinsable

Note: "DB-XLB is designed for inhibiting column bleed at high temperatures. It also appears to have
inadvertently inherited an exceptional ability for separating many PCB congeners when used with MS
detection. This stellar performance was maximized after careful optimization of the column dimensions,
temperature programs, and carrier gas flow conditions."
