GC COLUMNS | APPLICATION-SPECIFIC COLUMNS
Environmental
Rxi®-XLB Columns (fused silica)
(low-polarity proprietary phase)
• General-purpose columns exhibiting extremely low bleed. Ideal for many GC-MS
applications, including pesticides, PCB congeners (e.g., Aroclor mixes), PAHs.
• Unique selectivity.
• Temperature range: 30 °C to 360 °C.
