A novel spectroscopic method, named quartz-enhanced photoacoustic spectroscopy-conductance spectroscopy (QEPAS-CS), was first developed for gas mixture analysis. In QEPAS-CS, the advantage of photoacoustic detection and conductance analysis was realized by a quartz tuning fork (QTF). Two-component gas analysis was done by photoacoustic detection and conductance detection. For an explicit application, natural spider silk was used as a water vapor transducer to modify the QTF, making a conductance sensing channel. A 2004 nm laser diode was used as an excitation source for a photoacoustic sensing channel. Such a QEPAS-CS sensor was used for H2O/CO2 gas mixture analysis in a cell incubator. This provides a solution to calibrate an infrared photoacoustic spectroscopy gas sensor. This example effectively confirms the capacity of multigas analysis by the QEPAS-CS sensor.

用于气体混合物分析的石英增强光声光谱-电导光谱
一种新颖的光谱方法，称为石英增强光声光谱-电导光谱（QEPAS-CS），首先被开发用于气体混合物分析。在QEPAS-CS中，光声检测和电导分析的优势是通过石英音叉（QTF）实现的。通过光声检测和电导检测完成双组分气体分析。对于明确的应用，天然蜘蛛丝被用作水蒸气传感器来修改 QTF，形成电导传感通道。2004 nm 激光二极管用作光声传感通道的激发源。这种QEPAS-CS传感器用于H 2 O/CO 2细胞培养箱中的气体混合物分析。这提供了校准红外光声光谱气体传感器的解决方案。这个例子有效地证实了QEPAS-CS传感器的多气体分析能力。
