Rxi®-XLB (fused silica) columns are ideal for many GC-MS applications, including pesticides, PCB congeners (e.g., Aroclor mixes), PAHs.

• Ultra-low bleed
• Unique selectivity
• Temperature range: 30 to 360 °C

Ideal for analysing active, high molecular weight compounds. It is coupled with inertness and high thermal stability, make Rxi-XLB columns ideal for analysing semivolatile compounds in drinking water.
