Technobiochip has recently patented a series of poly-pyrrole derivatives. Here we report, for the first time, the development of a low-cost and sensitive colorimetric sensor array for the analysis of different volatile compounds in spirits and liquors using that derivatives. The identification is based on color intensity changes of poly-pyrrole derivatives sensor elements upon ligand binding. The data obtained revealed the sensor's ability for sensitive and specific detection of different type of VOCs, so providing a useful test for foods analysis and environmental monitoring.
