Abstract
For practical olfactory sensing with a safe and low-power system, it is important to be able to operate easily at room temperature. However, this has not been a trivial task to achieve with existing conventional gas separation and sensing devices. In this study, a novel compact room temperature-operated sensing system is proposed to separate and quantify each component in a vapor mixture with simple operation. The sensing system consists of a portable and replaceable gas separation column and a sensing module containing a nanomechanical Membrane-type Surface stress Sensor, MSS. Proton transfer reaction time-of-flight mass spectrometry (PTR-TOF-MS) results show that the gas separation column can clearly separate methanol and ethanol in their mixtures. The sensing signals from the column-MSS system are consistent with the peaks measured by PTR-TOF-MS. For mixtures of methanol and ethanol with various ratios, a clear correspondence is observed between the output signals and the theoretically calculated vapor pressure ratios of each mixture. The developed compact room temperature-operated sensing system can discriminate and quantify different methanol and ethanol mixtures, paving the way for practical applications of olfactory sensing devices.
