| Abstract: | An array,which consists of several piezoelectric crystal sensors,each coated with different absorptive and selective material,is presented to recognize aliphatic alcohol homologue and isomer of small molecular size.The frequency shift data obtained from the array as the response to the vapor of methanol,ethanol,2 propanol and 1 butanol are analyzed by using a principal component analysis method.The two dimension display of the original and auto stalled data shows well defined clusters for identical alcohol. |
