Abstract EN
Hexanal was identified as one of the major volatile gases which are produced in degraded dairy products and wood industries.
Therefore, preliminary study on hexanal gas detection with the laboratory scale was carried out in this paper.
Electrical testing with chitosan as a sensing material to sense hexanal gas in low concentration was carried out at room temperature.
Chitosan sensor was fabricated by using electrochemical deposition technique to form active sensing layer.
The response of the chitosan film sensor (CFS) towards hexanal was tested via electrical testing by exposing different hexanal concentrations ranging between 20 ppm, 100 ppm, 200 ppm, and 300 ppm using air as a carrier gas.
Sensing properties of the CFS toward hexanal exposure including responsibility, recovery, repeatability, stability, and selectively were studied.
Overall, our result suggested that hexanal sensor based on chitosan was able to perform well at room temperature demonstrated by good response, good recovery, good repeatability, good stability, and good selectively.
This simple and low cost sensor has high potential to be utilized in early quality degradation detection in dairy products and can be used to monitor the level of hexanal exposure in wood industries.
