SIMULTANEOUS DETECTION OF ORGANIC AND INORGANIC SUBSTANCES IN A MIXED AQUEOUS SOLUTION USING A MICROWAVE DIELECTRIC SENSOR

Abstract

This letter reports a new technique that enables simultaneous detection of concentrations of the organic and inorganic substances in a hybrid ∞uidic solution. The technique is based on a coplanar microwave distributed MEMS transmission line. Measurement results show that a hybrid aqueous solution with a mixture of 0M{0.2M NaCl and 0mg/ml{350mg/ml glucose can be easily detected simultaneously from measured one-port scattering parameter (S11).
