摘要
进行了溶剂介质对于激光光声和热透镜光谱信号增强研究,探讨了液体光声传感器压电换能元件不同组合装配方式对信号增强的影响,表明了增强作用机理。这对于激光光声和热透镜光谱分析在分析化学中的应用、提高灵敏度。
A study has been made on the enhancement of photoacoustic and thermal lens spectroscopic signals. The affection of the thermophysics property of the solvent for photoacoustic and thermal lens spectroscopic signals has been discussed. A method of enhancing the photoacoustic signals for piezoelectric transducer is described. It is important to enhance the sensitivity for photoacoustic and thermal lens spectrometry in analytical chemistry.
