Integra-Guard® built-in guard column
*Maximum temperatures listed are for 15- and 30-meter lengths. Longer lengths may have a slightly reduced
maximum temperature.
(fused silica)
(low to midpolarity phase; Crossbond® 6% cyanopropylphenyl/94% dimethyl polysiloxane)
• 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 stationary
phase available, with no other column manufacturer providing lower bleed, longer life-
time, or better inertness. Our polymer is fully characterized to ensure long-term repro-
ducibility, column-to-column consistency, and low bleed—even with sensitive detectors
such as ECDs and MSDs.

Rtx®-624 Columns
(fused silica)
(low to midpolarity phase; Crossbond® 6% cyanopropylphenyl/94% dimethyl polysiloxane)
• Application-specific columns for volatile organic pollutants. Recommended in US
EPA methods for volatile organic pollutants.
• Temperature range: -20 °C to 240 °C.
• Equivalent to USP G43 phase.
The unique polarity of the Rtx®-624 column makes it ideal for analyzing volatile organ-
ic pollutants. Although the Rtx®-502.2 column is recommended in many methods, the
Rtx®-624 column offers better resolution of early eluting compounds. The Rtx®-624
phase produces greater than 90% resolution of the first six gases in EPA Methods 8260
and 524.2. This stationary phase is especially well-suited for EPA Method 524.2 revision
IV since it resolves 2-nitropropane from 1,1-dichloropropanone, which share quantifi-
cation ion m/z 43 and must be separated chromatographically.
