• Megabore capillary columns are the most common columns used in environmental analysis. Some of the common capillary columns used for SVOC analysis include:
    • From J&W Scientific: DB-608, DB-1701, DB-5, DB-1, DB-Dioxin, DB- TPH, and dual column DB-17/1701P
    • From Hewlett Packard: HP-5, HP-1, HP-35, HP-1701, HP-608, and HP- 1301
    • From Restek: RtX-50, RtX-35, dual column RtX-1701/MXT-1701, and RtX-2330 (for dioxin), RtX-5/MXT-5 dual column

  • Some of the common capillary columns used for VOC analysis include:
    • From J&W Scientific: DB-624, DB-VRX, DB-5022, and dual column DB-624/VRX
    • From Hewlett Packard: HP-VOC and HP-624
    • From Restek: RtX-502.2, RtX-624, and dual column RtX-624/ MXT-624

  • An example of a stainless steel column is RtX-5, which is an unbreakable fused silica- lined stainless steel column. The column withstands higher temperatures and is used for analyzing for alcohols, ketones, and VOCs by purge-and-trap.
