## Title

- title: Compact Room Temperature-Operated Sensing System for Methanol and Ethanol
    Mixture Separation and Quantification
  title_type: original
  lang: en

## Description

- description: 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.
