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.

Compatible with Various Carrier Gases
As competition in the biofuels market increases, the need to reduce costs while maintaining quality is of major concern. The shortages of helium and its increasing costs have forced many labs to consider using alternative gases such as hydrogen.
The Zebron™ ZB-Bioethanol column is compatible with all carrier gases and will provide great separation no matter which gas you choose. To verify this, we ran several denatured fuel ethanol samples using various carrier gases. The results were virtually the same regardless of the carrier gas, proving the selectivity provided by the Zebron™ ZB-Bioethanol was not affected.
No resolution changes using different carrier gases
