Rtx®-1301
Rtx®-1301 (G43) Columns (fused silica)
(low- to midpolarity phase)
• General-purpose columns for residual solvents, alcohols, oxygenates, and volatile
organic compounds.
• Temperature range: -20 °C to 280 °C.
• Equivalent to USP G43 phase.
Many analysts feel the Rtx®-1301 column has the best cyanosiloxane bonded station-
ary phase available, with no other column manufacturer providing lower bleed, longer
lifetime, or better inertness. Our polymer is fully characterized to ensure long-term
reproducibility, column-to-column consistency, and low bleed—even with sensitive
detectors such as ECDs and MSDs.
*Maximum temperatures listed are for shorter length columns. Longer columns may have a different maximum temperature.
