Zebron ZB-BAC-2 GC Columns
Fast, Accurate Blood Alcohol Analysis
- Proprietary column set specially designed for accurate blood alcohol analysis — enhance resolution of ethanol and acetone peaks
- Resolves t-butanol and n-propanol for greater selection of internal standards
- Fast run time with baseline resolution of key components in just 2 minutes
- Achieve dual column confirmation - get two elution order changes with ZB-BAC-1
Need an alternate selectivity for blood alcohol confirmation? See ZB-BAC-1.
 
Testing drugs of abuse? See ZB-Drug-1.

In contrast, the Phenomenex Zebron ZB-BAC-1 & and ZB-BAC-2 columns were able to fully resolve both t-Butanol and 2-Butanol from other target analytes, while maintaining rapid analysis times. Quantitative analysis on the Zebron BAC pair showed equivalent performance between all three internal standards (n-Propanol, t-Butanol, and 2-Butanol). The LOD & and LOQ for this column set were far below the control limits required by current testing regulations.
