low- to midpolarity phase
The unique polarity of the Rtx-624 column makes it ideal for analyzing volatile organic 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 since it resolves 2-nitropropane from 1,1-dichloropropanone, which share quantification ion m/z 43 and must be separated chromatographically.
- Application-specific columns for volatile organic pollutants. Recommended in U.S. EPA methods for volatile organic pollutants.
- Temperature range: -20°C to 240°C.
- Equivalent to USP G43 phase.
