Oxygenate selective TIO-1 ionization provides easy
analysis of Ethanol amidst many Hydrocarbons of
Gasoline using a single Nitrogen supply for both GC
carrier and detector gas.

Oxygenate selective TIO·1 provides SPA detectivity
which is 50times better than an FlO.TIO·1 response to
Phenols, Carboxylic Acids, Glycols, Salicylates, and
Vanillin is especially large compared to other classesof
Oxygenates.
