Abstract
The article describes an instrument and a method for the characterization and validation of devices for instrumental odor measurement, especially miniaturized devices based inexpensive sensors. For this purpose, a test environment has been developed based on a combination of gas chromatography -mass spectrometry, odor measurement using olfactometry and sensor characterization. The system enables the connection of various gas sensors in a heated test chamber, which can be operated with an additional make-up gas flow. This allows testing conditions close to typical operating conditions, which is important for many sensor types e.g. metal oxide gas sensors. Our systems can measure rate constants for the kinetic processes on the sensor surface very efficiently allowing the modelling of virtual multi-sensors array using temperature-cycled operated (TCO). In this way, an optimized system approach can be quickly determined, set up and tested.
