Impact of Measurement Uncertainty on Modeling of Dielectric Relaxation in Aqueous Solutions

Uncertainty analysis is performed on a coaxial probe-based dielectric spectroscopy measurement platform, and its impact the modeling of relaxation in an aqueous solution further analyzed. Based characterization theory calibration principle uncertainty due to different available expressions parameters liquid calculated. Then, repeatability related drift environment change, position variation probe immersed under test (LUT), so Next, three types water–alcohol mixtures one group glucose solutions are measured using platform. results, best model chosen analyze frequency dependence solutions’ properties. In addition, based analysis, appropriate mathematical formulas provided composition parameters, which can be used as detection technique for chemical biological applications.
