Abstract :Solvents are widely used in daily life as well as in almost all laboratories. Identification and detection of these solvents used in many areas have great importance in terms of health, toxicology and environment. For this reason, the main purpose of our study is to be able to identify the solvents in practical ways. In this study, gold microelectrodes were used to define the capacitance detection of various solvents in the frequency range of 20 kHz - 2 MHz. Moreover, the electrical noise and signal output of the solvents at different frequencies were investigated. Measurements were made by micro-channels integrated on microelectrodes for reducing noises and detection with high sensibility.Keywords : Capacitive sensor, Micro channel, Coplanar electrode
