Split-ring resonator as detector for liquid and ion chromatography

The analysis of food and drugs, as well as the monitoring of chemical processes and bioreactors, requires the use of high-performance liquid chromatography (HPLC) and ion chromatography. These processes are best conducted with universal, cost-effective, and sensitive detectors. This project focuses on the use of a split-ring resonator, which detects changes in the electrical and dielectric properties of the eluate from liquid chromatography or ion chromatography by monitoring the amplitude of the transmitted signal using an envelope detector.
