    Abstract: 本研究利用石英晶體微天秤(quartz crystal microbalance , QCM)感測器陣列來結合主成分分析(principal component analysis,PCA)偵測毒性混合氣體(NH3,CO及NO2)製作一新穎簡單且快速之辨識系統。本實驗藉由氧化石墨烯,β環瑚精複合還原氧化石墨烯及N-取代吡咯衍生物複合金奈米粒子薄膜作為石英晶體微天秤陣列,分別測試不同濃度毒性氣體,並帶入主成分分析法以辨別毒性氣體訊號的特徵,建構模組,並加以測試三種混合毒性氣體。
    此次實驗結果顯示,使用低成本、容易使用及快速的方法可用於辨識混合毒性氣體已有初步結果,並可持續改良此系統。

    A novel quartz crystal microbalance (QCM) sensor array was fabricated for differentiating three toxic gases (NH3, CO and NO2) from their tertiary mixtures. The QCM sensor array composed of three QCM sensors that were constructed using graphene oxide (GO)-based and N-substituted pyrrole derivative-based films. The response frequency changes of a QCM sensor array were recorded upon exposing to each target toxic gas with varying concentrations and the obtained data were analyzed by principal component analysis (PCA) in order to differentiate the target toxic gas under testing condition of tertiary mixing of toxic gases. The results of this work show promising prospects for the use of a low-cost, easy to use and rapid method for differentiating the target toxic gas in the presence of a mixture of gases.
    Keywords: QCM sensor array; graphene oxide; N-substituted pyrrole derivative; differentiation of toxic gases.
