Rtx®-Dioxin2 Columns
(fused silica)
(proprietary Crossbond® phase)
• Isomer specificity for 2,3,7,8-TCDD and 2,3,7,8-TCDF achieved with one
GC column.
• Thermally stable to 340 °C for longer lifetime.
• Unique selectivity for toxic dioxin and furan congeners allows use as a
confirmation GC column.

“Using the Rtx®-Dioxin2 column
allowed us to combine EPA 1613
TCDD-only and TCDF confirmation
analyses onto one column and one
instrument. This resulted in multiple
benefits—we shortened run times,
reduced instrument downtime and
column changes, and increased instru-
ment capacity for our full list samples.”
