In this paper, we report the performance of a
volatile organic compounds identification system based on
a commercial metal-oxide gas sensor array. Analyses of
five volatile organic compounds (heptane, pentane,
isooctane, isopropyl alcohol, and tetrachloroethylene)
Have been performed with these unselective sensors. The
device consists of three MOX commercial sensors (ASMLN,
AS-MLK, AS-MLC), The behavior of these sensors
was measured at different ranges of temperature. Principal
component analysis (PCA) was applied in order to identify
the target gases. We obtained a high classification of the
five VOCs by temperature modulation. The final aim of this
research is to improve the selectivity of commercial sensors
based on metal oxide to classify different VOCs.
