Abstract

The gas sensing characteristics of Cr1-xFexNbO4 (x = 0.0, 0.5, 1.0) towards different organic analytes and hydrogen were investigated at different operating temperatures. The slope of the retrace transient, a representative feature for desorption kinetics was considered for data exploration. 11 sensors with 12 samples were tested and the data obtained was processed using principal component analysis (PCA). The scores plot and loadings plot showed the possible differentiation of the cross sensitive analytes and redundancy of the sensor behaviour towards these analytes respectively.
