Rtx®-BAC1 Columns
(fused silica)
(proprietary Crossbond® phase)
Rtx®-BAC1/Rtx®-BAC2
• Application-specific columns for blood alcohol analysis—achieve baseline resolution
in less than 3 minutes. Also excellent for abused inhalant anesthetics,
γ
-hydroxybu-
tyrate (GHB)/
γ
-butyrolactone (GBL), glycols, and common industrial solvents.
• Rtx®-BAC2 confirmation column provides four elution order changes under the
same conditions.
• Stable to 260 °C.
These columns separate to baseline all blood alcohol compounds in blood, breath, or
urine, in less than 3 minutes, under isothermal conditions. Isothermal analysis increas-
es productivity by eliminating the need for oven cycling. Confirmation is easily achieve
with this tandem set because there are four elution order changes between the tw
columns.
