GC COLUMNS | HIGH-PERFORMANCE RXI COLUMNS Rxi® Columns Overview Lowest Bleed Rxi® columns are more stable at high temperatures than any other manufacturer’s column (Figure 5), resulting in higher system sensitivity. This low-bleed characteristic is the result of superior stabilization achieved by optimizing polymer cross-linking and surface deactivation technologies. Benefits of using ultra-low bleed Rxi® columns include: • Increased sensitivity, for lower detection limits and better matches to mass spectral libraries. • Faster system stabilization. • Reduced detector contamination and less downtime for maintenance. Figure 5 Rxi® columns have the lowest bleed among all major brands of columns. 20.0 17.5 Improve sensitivity and accuracy at trace levels with low bleed Rxi® columns.

Exceptional Reproducibility Chromatographers today need to know that every column they receive is going to perform the same way as the column it replaces. Unmatched manufacturing precision and stringent quality control mean Rxi® columns exceed industry standards, resulting in the best column-to-column reproducibility available as measured by efficiency, retention, bleed, and inertness (Figure 6). Figure 6 Rxi® columns are engineered to assure column-to-column and lot-to-lot reproducibility. 1 2 3 4 5 6 7 8 Column 722883 Batch #1 Column 717989 Batch #2 Column 720331 Batch #3 GC_EV00819 Column: Rxi ® -5ms, 30m, 0.25mm ID, 0.25µm (cat.# 13423) Sample: 500µg/mL Isothermal Column Test Mix in toluene Inj.: 1.0µL, split injection (split ratio 1:100), 4mm single gooseneck inlet liner with wool (cat.# 22405) Inj. temp.: 250°C Carrier gas: hydrogen, constant flow Linear velocity: 38cm/sec. @ 135°C Oven temp.: 135°C Det.: FID @ 330°C 1. 1,6-hexanediol 2. 4-chlorophenol 3. methyl nonanoate 4. 1-decylamine 5. tridecane 6. 1-undecanol 7. acenaphthylene 8. pentadecane www.restek.com 39 Website : www.chromtech.net.au E-mail : info@chromtech.net.au TelNo : 03 9762 2034 . . . in AUSTRALIA Mar 2011
GC COLUMNS | HIGH-PERFORMANCE Rxi COLUMNS Rxi® Columns Overview Column Cross-Reference Table Rxi® columns produce the same selectivity as competitor columns, but are much more inert, exhibit lower bleed, and offer exceptional reproducibility.
