Laboratory characterization of metal‐oxide sensors intended for <i>in situ</i> analyses of pheromones – SOMMSA approach

Abstract

Abstract We present pheromone measurements of metal‐oxide gas sensors in a laboratory setup using a ‘selective odorant measurement of a multi‐sensor array’. The array was equipped with commercial gas sensors and measured with constant temperatures and a temperature cycle to increase the sensitivity. To compare and to calibrate the measurement of insect pheromones, we used a portable GC‐MS with an electro‐antennographic detection system for insect antennae. In order to reach a proof of principles for the intended use of the system for in situ analyses in viticulture and the development of a portable biosensor, we tested the sensors with the main component E7,Z9‐Dodecadien‐1‐yl acetate of the pheromone of the grapevine moth ( Lobesia botrana ).
