The analysis of the pore filling degree of supported ionic liquids (ILs) is essential for industrial applications. In this study, two methods to detect the loading of IL supported on solid carriers are presented, a radio frequency-based one and one using impedance spectroscopy. With the radio frequency-based method, the pore filling degree can be determined contactless and in operando. Some unexpected deviations at non-relevant high pore filling degrees occur. They can be explained by the combination of the results from the radio frequency-based method (at 1.2 GHz) and the impedance spectroscopy (at 1 Hz to 2 MHz). A transition from low polarization losses to high conduction losses occurs with increasing ionic liquid loading of the porous carrier.

对负载型离子液体（ILs）的孔填充度的分析对于工业应用至关重要。在这项研究中，提出了两种检测固体载体上负载的IL的方法，一种是基于射频的方法，另一种是使用阻抗谱的方法。使用基于射频的方法，可以非接触地并且在操作中确定孔的填充程度。在不相关的高孔填充度下会发生一些意想不到的偏差。可以通过基于射频的方法（在1.2 GHz时）和阻抗谱（在1 Hz至2 MHz时）的结果相结合来解释它们。随着多孔载体的离子液体负载的增加，发生了从低极化损耗到高传导损耗的过渡。
