具有性能化学品（如离子液体（IL））的混合物的VLE数据的知识对于技术应用是非常重要的。这项研究提供了新的见解，利用石英晶体微天平（QCM）的可靠吸收测量离子液体。Sauerbrey方程对刚性薄膜和液体的有效性在文献中得到了广泛的讨论。这项工作表明，如何确保Sauerbrey方程的有效性在吸收测量薄液膜。此外，在薄液膜内的吸收测量相比，抛光的就业粗糙的电极的优点进行了详细描述。提出了应用QCM系统进行重力测量的重要建议。
The knowledge of VLE-data of mixtures with performance chemicals, such as ionic liquids (ILs), is very important for technical applications. This study provides new insights into the utilization of quartz crystal microbalances (QCM) for reliable absorption measurements in ILs. The validity of the Sauerbrey equation for rigid films and bulk liquids is widely discussed in literature. This work shows how to ensure the validity of the Sauerbrey equation during absorption measurements in thin liquid films. Furthermore, the advantages of the employment of rough electrodes for absorption measurements within thin liquid films in comparison to polished ones are described in detail. Important recommendations in application of the QCM systems regarding gravimetric measurements are presented.
