Calibration of (commercial) e-noses.
One of the research lines of the Applied Nanotechnology research group (Saxion, Enschede) focuses on the development of gas sensors and more specifically on the development of an e-nose system for the early detection of parasitic infestation in chicken farms. An e-nose consists of an array of sensors and by cleverly combining the signals produced by the individual sensors allow the detection of specific molecules with high selectivity and sensitivity.
In this project the aim is to determine the selectivity, sensitivity and stability of the various gas-sensors that have been combined in the e-nose systems we have developed. The specifically developed gas-supply set-up (‘owlstone’) allows to control to a very high degree the concentration of the gas (mixtures) that are supplied to the sensor(s). Initially the project will focus on the single components that make up the atmosphere in a chicken shed (e.g. ammonia or humidity), shifting to more complex mixtures of gasses with the aim to mimic the actual conditions in the shed.
The outcomes of this study will yield essential information on the performance of the individual sensors and thereby on the performance of the e-nose as a gas-sensor.
