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).
Use Rxi® Guard/Retention
Gap Columns to protect
your analytical column and
help focus analytes.
Rxi® Guard/Retention Gap Columns (fused silica)
• Extend column lifetime.
• Excellent inertness—obtain lower detection limits for active compounds.
• Sharper chromatographic peaks by utilizing retention gap technology.
• Maximum temperature: 360 °C.
