Agilent DB-VRX Capillary GC Columns

By Agilent Technologies
Agilent DB-VRX Capillary GC Columns

The DB-VRX handles the extensive target list of volatiles in less than half the time as standard 105m columns, with very few coelutions. Use the DB-VRX (and DB-624) for EPA methods 502.2 and 8021.

  • Unique selectivity engineered for optimum resolution of volatiles analysis: U.S. EPA Methods 502.2, 524.2 and 8260
  • 0.45 mm ID columns provide more plates per meter compared to 0.53 mm ID columns for the fewest coelutions for GC method**
  • No subambient cooling required to resolve the six "gases"
  • Fast run time: < 30 minutes for optimum sample throughput; < 8 minutes with 0.18 mm ID
  • Low polarity
  • Excellent peak shape
  • Bonded and cross-linked
  • Solvent rinsable

** Two coelutions: 1) m- and p-xylene, for which U.S. EPA does not require separation, and 2) 1,1,2,2-tetrachloroethane and o-xylene, which are separated by detectors PID and ELCD, respectively. Note to GC/MS analysts: These coeluting compounds have different primary characteristic ions of 83 and 106, respectively.

Temperature limits -10 to 260°C.
