These gas chromatography columns are designed for the analysis of volatile organic compounds using a GC/MS system.

• Well-suited for EPA method 524.2
• Application-specific columns for volatile organic pollutants
• Rtx®-624 phase produces greater than 90% resolution of the first six gases in EPA methods 8260 and 524.2

Equivalent to USP G43 phase

Phase composition: crossbonded 6% cyanopropylphenyl, 94% dimethylpolysiloxane. Temperature range: −20 to 240 °C (−4 to 464 °F). Recommended for EPA methods 502.2, 524.2, 601, 602, 624, 8010, 8020, 8240, and 8260.

Application-specific columns for volatile organic pollutants. 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.
