Selective Detection of Aromatic Compounds with a Re-Designed Surface Acoustic Wave Sensor System Using a Short Packed Column

A self-developed and newly re-designed chemical SAW sensor system composed of four polymer-coated differently modified nano-diamond-coated sensors was applied to measure aromatic compounds in gasoline a low-cost, fast, easy way. An additional short packed column at the inlet improve selectivity for various possible fuel applications. The allows direct sampling liquid fuels pre-separates different components groups (aromatic aliphatic compounds) from sample. Since employed show linearity towards concentration, an quantification single even within group compounds.
