GC COLUMNS | HIGH-PERFORMANCE RXI COLUMNS
Rxi®-XLB, Rxi®-35Sil MS, Rxi®-17 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. ID 0.25mm

tech tip In combination with an Rxi®-XLB column, simple adjustments to the injection conditions can greatly improve sensitivity for active and high molecular weight Method 525.2 target compounds. By eliminating contact between the sample and the hot metal surfaces in the injection port, a Drilled Uniliner® inlet liner prevents analytes from degrading in the injection port.
