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.
