Zebron ZB-Bioethanol
- Resolve methanol and ethanol from all other denaturant peaks
- With analysis time down to 5 minutes, complete certificate of analysis (COA) before fuel truck leaves
- Major cost savings over the standard 100 meter GC columns
Zebron ZB-Bioethanol columns provide bioethanol analysis in less than half the time of standard GC columns. Using this new, specially designed phase, resolution of methanol and ethanol from a sample denatured with gasoline can be achieved in less than 8 minutes. In fact, the column provides such great resolution that the analysis can be reduced to less than 5 minutes by using a 15 meter column. This dramatic time savings gives you the ability to test the fuel trucks before they leave the facility reducing the chance for potential problems.

Great Resolution of Fuel Alcohols Products
Since gasoline is a very complex mixture and contains many low boiling components that could potentially co-elute with methanol and ethanol, the resolution provided by the Zebron™ ZB-Bioethanol column was confirmed using GC-MS. As you can see, the methanol and ethanol peaks are well resolved from all potential interferences.
