A new multisensor headspace and electronics for gas detection are presented. The system is PC-based and fully software controllable and reconfigurable. It was designed to allow for a very versatile use with different metal oxide sensor elements. In particular, the system supports different measuring techniques such as sensor impedance measurement in a frequency range spanning from DC to 15 MHz, and sensor gas sensitivity measurement when the temperature follows an arbitrary-defined trend. Some preliminary results concerning wine classification are also presented.
